That is all for today's live text coverage. Thanks for joining, goodbye!
Tuchel's side are now three points better off than West Ham in fifth, though they have played two games more than both their London rivals and Everton, who are five points worse off. Next up for Chelsea is a Champions League last-16 tie with Atletico Madrid on Wednesday, while Leeds - now within two points of the top half - head to Fulham on Friday.
Chelsea drop two points in the top-four battle with a goalless draw at Leeds. Roberts had a goal ruled out in the first half and hit the crossbar, while Llorente hit his own bar from the visitors' best moment of a rather disappointing game. The closest either side came to a second-half winner was Rodrigo's weak header 12 minutes from time.
90' + 4' FULL-TIME: LEEDS UNITED 0-0 CHELSEA
90' + 3' Hudson-Odoi has room to get a shot away 15 yards out but he is reluctant to do so. Instead he attempts a throughball, which trickles out of play for a goal-kick.
90' + 2' Chelsea win a late corner, which Werner heads back into the middle. It drops for Azpilicueta but he cannot do anything with it. That may well be that.
90' + 1' Christensen does well to block Raphinha's cross. The ball ricochets back off the Leeds man for a goal-kick.
90' Three minutes have been added on at the end of match at Elland Road. There is still time for a winner.
89' Christensen goes on another run through the middle. The defender tries to slip the ball through for Hudson-Odoi but completely overhits it.
88' SAVE! Like fellow substitute James, Hudson-Odoi's fresh legs are making a difference. He brings the ball inside two opponents, drops the shoulder and fires in a shot that is near enough right at Meslier.
87' James is desperately trying to make something happen for Chelsea. He knocks the ball past two men and is tripped by Dallas, who is given a warning by the referee.
86' We are into the final four minutes of normal time at Elland Road. Both managers have made all three substitutions and there is not a great deal happening out there at the moment.
84' Chelsea are the side pushing for a winner, but they are not exactly creating a great deal at the moment. Indeed, Leeds squandered the best opportunity to snatch all three points through that weak Rodrigo header.
82' Hudson-Odoi is playing up top. A poor first touch lets him down when played through, but the offside flag would have denied the substitute anyway.
81' Chelsea boss Thomas Tuchel is unbeaten in his nine Premier League games so far - only Maurizio Sarri (12) and Frank Clark (11) have had longer runs without defeat from the start of their Premier League careers.
78' FREE HEADER! What a chance to win the game! Rodrigo pulls off Mount and is completely unmarked 10 yards out to meet the corner. The substitute striker sends his header straight down the middle and Mendy has a straightforward save to make.
77' DEFLECTED OVER! Some rare Leeds pressure almost culminates in a goal. Roberts gets in behind and pulls the ball back for Llorente. The shot hits James and deflects over the crossbar for another corner.
74' The game has become incredibly scrappy now. Chelsea are running out of time to find a breakthrough.
73' GOOD ATTEMPT! Rudiger decides to have a go from range. It gives Meslier something to think about but the Leeds keeper is able to parry the ball to safety.
71' Ayling seems to be okay to play on after shaking off the injury sustained from the challenge with Rudiger.
70' While those Chelsea substitutions were being made, Ayling was down receiving some treatment. Will Bielsa be forced into making another change?
67' Pulisic pokes the ball away from the feet of Raphinha before the Leeds attacker can get a shot away at the back post. Great defending!
66' Werner and Giroud are warming up and may be about to come on for Chelsea. Tuchel will see this as two points dropped in the battle for a top-four finish should it finish this way.
63' Chilwell picks up the ball in a bit of space. He has a chance to get a shot away but, under pressure from a couple of Leeds plays, he completely miscues the attempt wide from 12 yards.
62' Raphinha sends in a teasing free-kick from deep into a dangerous zone. Yet again, it is Chelsea centre-back Rudiger who gets his head to it first.
60' SHOT! Leeds have had more shots (two) so far in the second half compared to the whole of the first half (one). Chelsea are looking the more likely side to score, though, as Pulisic tests Meslier at his near post.
58' Chelsea have lost away to a promoted club in each of the last three Premier League seasons (Newcastle United 2017-18, Wolves 2018-19, Sheffield United 2019-20). They have never done so in four consecutive campaigns in the competition, already drawing at West Brom and winning at Fulham so far this season.
56' GOOD SAVE! End-to-end stuff at Elland Road now. Raphinha's shot bounces off the floor - always an awkward one for goalkeepers to deal with - and Mendy adjusts well to get a strong hand to the ball.
54' A nervy minute or so at the back for Leeds. Chilwell and then Ziyech send in dangerous crosses and Kante pulls the ball back into a dangerous zone, though the midfielder should probably have been looking to take on the shot.
52' Havertz had a big chance a few minutes ago, but that aside it has been a low start to the second half. A goalless draw would suit Leeds more than their opponents, it must be said.
50' SHOT! Roberts cuts inside on his right foot and gets a shot on target. The effort lacks any real power and Mendy makes a routine stop down low.
48' BIG CHANCE FOR HAVERTZ! The Chelsea forward sets himself for a clean shot on goal with a good first touch, but he is too slow to get a strike away and Meslier palms the ball over the bar when it does eventually arrive. He should be burying that.
47' Neither manager made any changes at half-time, incidentally, so it is as you were from the end of the opening 45 minutes.
46' RESTART! Chelsea, who can move up to third with a victory here, get us back under way at Elland Road.
Chelsea are on course for another clean sheet, but they have not really managed to stamp their authority on the game with this four-man defence. Tuchel made six changes to his line-up today and may be tempted to tweak things at the interval. As for Leeds, who lost Bamford to injury, Bielsa will be after more of the same.
Leeds and Chelsea go into half-time goalless. Roberts had a goal ruled out for offside against Bamford and then hit the crossbar, while Chelsea's best moment arrived 10 minutes in when Ayling's clearance bounced off team-mate Llorente and hit the frame of the goal.
45' + 2' HALF-TIME: LEEDS UNITED 0-0 CHELSEA
45' + 1' CHANCE! One minute has been added on at the end of the first half. Havertz makes a good run in behind and connects with a pass through the Leeds backline, but he cannot fire it past Meslier.
45' Chelsea's pressing pays off as Meslier kicks the ball straight out of play for a throw. The visitors have looked lively in spells today but need to improve in the second 45.
43' Chilwell has time to pick out a team-mate. He hangs a cross into the six-yard box and Meslier gets to it ahead of Rudiger.
41' SAVE! It is a first real stop of the game for Meslier to make. Mount has far too much time and space and pulls the trigger from 25 yards. It is rather central and Meslier keeps it out at the second attempt.
39' The corner drops at the feet of Rudiger. The defender does not have time to properly react and the ball pretty much rolls to Meslier to gather.
37' Ziyech is picked out on the right by a long ball over the top from Mount. The Morocco international tries to bring it inside but the best he can manage is a corner.
35' Bamford is down once again and his game is surely up. Leeds will have to make a change with 10 minutes of the half to play.
34' Chilwell's shot from 20 yards is inches wide of the target, with Meslier not getting to it at full stretch. It took a small touch on its way through as a corner has been awarded.
33' Bamford is back on the field - for now. Rodrigo has been sent to warm up but Leeds will remain unchanged for the time being.
32' Leeds striker Bamford has tried to run off the earlier knock he sustained in a challenge with Rudiger but has now stayed down. The physios are on and there will be a stoppage in play.
30' Bamford picks up another knock and is limping quite heavily. Bielsa may well be forced into a change up top.
29' SHOT! Kante has space to turn, run and shoot. The shot deflects off Struijk and goes behind for a corner, which is played straight through the box without a touch.
27' The rain is really starting to come down at Elland Road now. Chelsea have had 61 per cent of the ball but have managed just two shots so far, one of those on target - the same number as Leeds.
25' Chilwell's cross from the left is glanced on by Pulisic but is just out of Havertz's reach. Pulisic is everywhere for Chelsea at the moment.
22' Another great ball in from the left is again dealt with by Rudiger with Bamford right behind him. Leeds are starting to turn the screw.
21' Rudiger gets his head to a cross from the left before Bamford can pounce. Good defending from the Chelsea centre-back.
20' Pulisic is having a good game, but Chelsea's other attacking players have not offered a great deal so far. Leeds have edged the opening quarter of the game and perhaps should be ahead.
18' Of the 48 opponents Chelsea have faced away from home at least 15 times in all competitions, the Blues' lowest win rate is against Leeds United (14 per cent - P49 W7 D14 L28).
16' OFF THE BAR - AGAIN!! Roberts tries to pick out the top-right corner with a curler and comes within inches of doing exactly that. The ball crashes back off the crossbar, with Mendy perhaps getting the smallest of touches to it.
15' Pulisic is causing Leeds all sorts of problems down Chelsea's right. He gets the better of Alioski once again - as he did for the earlier Havertz chance - and his cross is only half dealt with by Meslier. No Chelsea player is around to convert the loose ball.
13' It has been a lively start to the game at Elland Road, with Chelsea missing a good chance and hitting the crossbar, while Leeds have had a goal ruled out. More of this!
11' OFF THE BAR! It is almost a disastrous moment for Leeds! Ayling's clearance bounces off Llorente back towards his own goal. The ball hits the crossbar and lands in the welcoming hands of Meslier.
10' Ayling did well to put off Havertz, but the Chelsea forward really should have been making more of that chance. As for the disallowed Leeds goal, Bamford was just offside so that was a good call from the officials.
8' GOAL RULED OUT!! Havertz fails to connect with Pulisic's cross and 17 seconds later the ball is in the net at the other end. Bamford is played clean through and squares for Roberts to tap into an empty net, but the offside flag goes up to cut short the celebrations.
6' Chelsea are enjoying a sustained spell of possession. They work it through the middle and down the left but there are no gaps to exploit in the Leeds backline.
4' Dallas goes in hard on Chilwell but the Chelsea left-back seems to be okay. Phillips has sustained a knock early on for Leeds, too.
2' It looks like being a 4-2-3-1 for Chelsea, with Azpilicueta at right-back. Leeds are shaping up in their familiar 4-1-4-1 formation.
1' KICK-OFF! Leeds, who can draw level on points with Arsenal in 10th place with victory today, get us up and running at Elland Road!
Both sets of players are on the field at Elland Road and kick-off is now just a few moments away in this first of four Premier League fixtures today.
Leeds United have lost just one of their last nine Premier League home games against Chelsea (W5 D3), with this the first such meeting since a 1-1 draw in December 2003. Chelsea are looking to secure their first league double over Leeds since the 1988-89 campaign in the second tier.
Chelsea show six changes from their win against Everton earlier in the week, as well as a change of formation. Chilwell, Rudiger, Kante, Mount, Ziyech and Pulisic return to the line-up, having all been named among the subs last time out, which only highlights the strength in depth available to Tuchel. Werner is among those to make way, possibly with next week's clash against Atletico Madrid in mind.
Bielsa has made three changes to Leeds' starting line-up following the loss to West Ham five days ago. Captain Liam Cooper misses out today through injury, so in comes Struijk alongside Llorente in the heart of the back four. Klich and Costa drop to the bench, meanwhile, with Alioski and Harrison recalled to the XI. Bamford is making his 100th appearance for the club.
Subs: Marcos Alonso, Kepa Arrizabalaga, Timo Werner, Reece James, Callum Hudson-Odoi, Mateo Kovacic, Olivier Giroud, Emerson Palmieri, Kurt Zouma.
CHELSEA XI (4-2-3-1): Edouard Mendy; Cesar Azpilicueta (c), Andreas Christensen, Antonio Rudiger, Ben Chilwell; N'Golo Kante, Jorginho; Hakim Ziyech, Mason Mount, Christian Pulisic; Kai Havertz.
Subs: Robin Koch, Rodrigo Moreno, Helder Costa, Jamie Shackleton, Jack Jenkins, Gaetano Berardi, Ian Poveda, Mateusz Klich, Kiko Casilla.
LEEDS XI (4-1-4-1): Illan Meslier; Luke Ayling (c), Diego Llorente, Pascal Struijk, Ezgjan Alioski; Kalvin Phillips; Raphinha, Tyler Roberts, Stuart Dallas, Jack Harrison; Patrick Bamford.
Chelsea remain unbeaten in 11 matches under Thomas Tuchel following their 2-0 win over Everton on Monday. That includes a run of six wins and three draws in the Premier League under the German coach, seeing them climb into the top four.
Leeds have lost four of their last five league matches, most recently going down 2-0 to West Ham on Monday. Marcelo Bielsa's side may have struggled for form in recent weeks, but they enter this game just three points off the top half.
