That's all from this one, where Juve have secured another three points towards their title tilt. Thanks for joining us and, until next time, goodbye!
The Bianconeri will look for Lazio's result against Fiorentina tomorrow with great interest before preparing to face Genoa on Tuesday. Lecce would welcome a Juve win there as their relegation battle continues with a crucial clash at home to Sampdoria.
Juve have won 4-0 to go seven points clear at the top of Serie A, but the scoreline does not quite tell the whole story. Lecce gave as good as they got in the first half, even with Lucioni dismissed after 31 minutes. And not until Dybala's sublime strike on 53 minutes did Juve get a lead they would never relinquish. Ronaldo, wasteful up to that point, won and dispatched a penalty before teeing up Higuain, with De Ligt adding the fourth.
90' + 1' FULL-TIME: Juventus 4-0 Lecce
90' Lecce want a late consolation. Calderoni carries the ball forward but drags a poor shot well, well wide. That should be that.
88' Now Gabriel saves again, albeit from a tamer shot as Higuain's attempt deflects through to the grateful goalkeeper.
87' SAVE! Gabriel remains determined, even with the goals flying in. He gets up to deny Costa a well-earned strike.
81' Lecce occasionally see an opportunity to counter, continuing to pursue chances in attack. But Szczesny has enjoyed a really straightforward second half, simply sweeping up the odd long ball.
79' APPEAL! Ronaldo furiously believes he should have a penalty! The Juve star actually handles Costa's inviting cross but only after appearing to have been dragged down by Rispoli. No foul given.
78' WIDE! Higuain is involved straight away, drilling a shot wide. Juve have not slowed since the goals, improving against tired legs if anything.
75' SAVE! Gabriel is determined to keep the score down! A lovely turn from Ramsey opens up space for a shot just inside the area after a spell of further Juve probing, yet his effort is parried clear.
71' SAVE! Gabriel is being kept busy! This is another really good save, stooping to tip De Ligt's drive around the post. The corner comes to nothing.
70' To their credit, Lecce are still attempting to play out from the back. But they started this match with a deep, deep defensive line and their tired legs are not getting any further up the pitch.
69' SAVE! Great stop from Gabriel! Matuidi swings in a stunning cross, finding Ronaldo unmarked and with time and space to pick his spot with the header. Unlike in the first half, he hits the target, yet an instinctive hand from the goalkeeper keeps the ball out.
67' Juve are not yet happy with their lot. They win a free-kick on the left, which Dybala takes. He so nearly picks out a lunging Bonucci, with the ball also bouncing beyond Ronaldo behind him.
64' Babacar looks to make an immediate impact but sends a weak shot straight at Szczesny.
62' Lecce become the 20th of 21 Serie A opponents Ronaldo has scored against.
61' PENALTY! A blatant foul on Ronaldo, who can now make it two! He beats Rossettini to a square ball, getting a touch and tempting the challenge.
60' Szczesny is stood 40 yards from his own goal as Juve attempt to keep Lecce penned in. Ronaldo might well have an opportunity to score but for a wonderful lunging clearance from Rossettini deep inside the area.
58' Easy stuff for Gabriel. Matuidi chooses not to look for a team-mate as he instead shoots from 25 yards, picking out the goalkeeper's gloves.
57' A dash up the right brings Lecce brief hope of pushing Juve back, yet no foul is given following a clash and the champions can instead attack once more. Ronaldo is now stationed inside the Lecce box.
55' This could be a long second half for 10-man Lecce now. Juve want another to put this game to bed.
54' Dybala has now been directly involved in at least one goal in five straight Serie A matches in the same season (four goals and one assist) for the first time since January 2016. This was also his 50th home goal in Serie A.
52' Costa has a swift impact! Darting down the right, he gets to the byline and cuts a cross back that somehow evades everyone in the centre.
51' CLOSE! Cuadrado's cross wins a corner, and Sarri pauses a proposed substitution. The set-piece goes short to Dybala, who fizzes a shot across the face of goal.
50' The tone is set for this second half. Juve are camped in the Lecce half, but Mancosu and Falco are working hard to provide an out ball. Rabiot's foul on the former lets Lecce regroup.
48' SAVE! Nervy moments at the back for Lecce! A right-wing cross lands on the head of Bonucci, whose low effort is parried by Gabriel. Lecce are scrambling but eventually clear for Falco to win a free-kick and some respite on halfway.
47' Juve's early efforts are thwarted as Matudui clashes with Rispoli, who wins a free-kick and requires treatment but can continue.
46' KICK-OFF: We are back under way, with Juve in possession and in pursuit of a precious winner.
Even with Juve clear at the top of Serie A, coach Sarri remains under pressure. Performances like this are unlikely to ease his situation. For all that Lecce have played well and Juve still should have scored twice, the Bianconeri have been really poor.
Well, that turned out to be a gripping half of football, even if it remains goalless. Lecce were the better team for half an hour until Lucioni was sent off following a poor error just inside his own half. Juve then had two huge chances to take the lead - through Ronaldo and then Bernardeschi - but quite incredibly squandered both.
45' + 3' HALF-TIME: Juventus 0-0 Lecce
45' + 2' De Ligt cannot aim a header on target after Ronaldo's pressing on the left wins a corner from Rispoli. It is a difficult chance, leaning back 12 yards out.
45' + 1' There will be a minimum of two minutes of added time.
45' + 1' Really good defensive work from Bentancur. A Lecce player beats De Ligt to a 50-50 on halfway, allowing the visitors to break. But Bentancur, on a booking, races back to fairly dispossess Falco.
45' Juve are growing frustrated - somewhat understandably. Bentancur goes for goal from 20 yards but gets the shot all wrong.
43' AND AGAIN! This is quite staggering! How are Juve not in front?! Ronaldo turns provider, drilling in a low cross that Bernardeschi needs only to turn into the net. He somehow blazes over. Juve have missed two massive chances to take a lead late in this half.
41' WHAT A MISS! Ronaldo! Incredible! Pressure is building on the Lecce goal, and the defenders stand still as a corner lands on Ronaldo's forehead six yards out. With goalkeeper Gabriel rooted, he remarkably heads over the crossbar. The forward cannot believe it.
40' Gabriel comes for the set-piece and, along with the help of a defender, gets just enough on the ball to get it clear. Juve build again, though, and Dybala is next to cross and win a corner.
39' Lecce just need to be careful in possession in their own third. They work out of trouble smartly, only for Tachtsidis to dally and lunge into a challenge that his opponent wins. Matuidi's cross is deflected, giving Juve a corner.
38' This is a real waste. The free-kick is nudged square to Vera, yet he blasts a poor shot well off target.
36' A well-timed tackle from Tachtsidis on the edge of the area frustrates Ronaldo, but Juve soon win a corner on the right. De Ligt is the man to go down this time, yet no foul is given in the centre.
34' WIDE! There is no change in the 10-man visitors' approach for now! They pump the ball into the box from a free-kick and work hard to ensure Juve cannot recover. Space eventually opens up for Tachtsidis to let fly from the edge of the area, yet his shot slices wide.
33' Ronaldo surprisingly chooses not to shoot from the free-kick following the red card, and Juve cannot work an opening. They should be in complete control now, though.
30' But back come Lecce. A teasing ball from the right causes the Juve defence some problems, with a hurried clearance only allowing the away team to build again.
29' WIDE! Ronaldo is just growing into the game. Moments after a failed overhead-kick, he sends in a low left-footed shot that fizzes wide. Gabriel is briefly scrambling.
28' Not this time! Ronaldo moves down the left and crosses, his ball passing through to Bernardeschi on the far side. The right-sided winger lifts a delivery back across for Ronaldo, who attempts a spectacular overhead-kick. The forward does not catch this one sweet, though, and the ball skews wide.
27' Lecce counter at speed, but Rispoli ignores his team-mates to aim a tame shot straight at Szczesny. The visitors would do well to make the most of their opportunities.
26' Bernardeschi is flagged once more on the right wing. This is poor positional play rather than a mistimed run. He is finding space behind Vera but has not been able to exploit it yet.
25' Juve captain Bonucci is eager to get his team going. He is forward in the left wing position to take a throw-in as the hosts aim to play with greater urgency.
23' Bernardeschi is at least offering Juve an outlet. As in the opening moments, he runs in behind on the right, only to be flagged offside.
22' Rispoli lofts a cross into the Juve area, with Mancosu unmarked for a moment as he leaps for the ball. Two defenders step in to clear, conceding a corner. It comes to little this time, though.
20' SAVE! Good work from Gabriel! Juve look to press on in pursuit of an opener and Rabiot takes aim from 25 yards, drawing a diving stop from the goalkeeper.
19' WIDE! A Juventus corner from the right goes short but only wins another set-piece, which proves more effective. Bentancur meets the ball with a header across goal, but it drops wide.
18' Lecce go short with the kick before eventually crossing from a similar position, with Cuadrado up to head clear. Juve can counter three on one, but Ronaldo's pass is poor and a team-mate can only rescue a corner.
17' Rispoli gets to the corner flag and wins a set-piece as his cross deflects behind off Matuidi. Maurizio Sarri looks a little concerned.
16' Simple stop for Szczesny, but Lecce move the ball nicely again in response to Juve's probing. A gorgeous switch onto the toe of Rispoli gets Lecce up the pitch, before Pertriccione looks left. Mancosu works space for a low shot, but the goalkeeper gathers.
14' Juve are just starting to take control of the match, but they are being frustrated in their attempts to break Lecce down. Cuadrado swings over a cross that goes straight out of play.
13' Ronaldo wins a free-kick from Petriccione, which Dybala sends into a dangerous area. A defender beats Ronaldo to the ball, though, as the Juve star protests on the ground.
11' Lecce have had 47 per cent of the possession and the only shot of the match so far. Not bad for a visiting team at Juve.
9' Juve move down the right through Bentancur, but a Lecce defender goes down in the centre as he tussles with Rabiot under a high cross. A free-kick is given against Juve.
8' Lovely from Lecce once more. Tachtsidis teases a smart pass into the Juve area, but Falco cannot quite work an angle for a shot. The better play is coming from the strugglers.
6' Juve appeal in vain as Vera goes up for a header following a long ball and seemingly misses it entirely. The home players think he does get a touch, meaning a corner, but the officials disagree.
5' Falco is just a step offside as Lecce look to get in behind the Juve defence on this occasion. This is a bright start from the visitors.
4' CLOSE! What a move! Lecce are happy to take risks in possession, attempting to play out from deep inside their own area. It works, though. As they work up the pitch, Mancosu nods a header down for Falco, who flicks a pass into Rispoli's path. He lashes off target.
3' Bernardeschi almost gets in, but he strays just offside! The winger marginally beats Gabriel in a race with the goalkeeper for the ball on Juve's right, yet the ball bounces behind and the flag is up.
2' Unsurprisingly, Juve have quickly taken control of the possession, pinging early passes around the midfield.
1' KICK-OFF: Lecce get us under way!
The two most recent meetings between these sides have ended level. Lecce are today aiming to go three unbeaten against Juve for the first time in their history.
Alex Sandro and Mattia De Sciglio are injured, while Danilo is suspended, meaning Matuidi is forced to fill in at left-back for Juve. Ahead of him, Ronaldo appears set to continue in a left-sided role, with Dybala through the middle and Bernardeschi keeping his place on the opposite flank.

Let's get the team news from Turin...
Lecce need the points, too, though, as they sit 18th, level on points with 17th-placed Genoa. Their form either side of the pause in the season has been slightly bizarre, winning three in a row - including a victory at Napoli - before losing their next three, conceding 15 in the process.
Defending champions and league leaders Juve are looking to stretch their advantage at the summit to seven points with victory. Title rivals Lazio threw away a two-goal lead to lose to Atalanta in midweek after the Bianconeri had beaten Bologna.
