114' Oliveira is brought down by McKennie, and the away side have a free-kick in a dangerous central area. Oliveira will take it...

111' Kulusevski’s shot from left side of the box cannons out for a corner off Manafa. Bernardeschi takes it short, but Corona easily regains possession from the Swedish attacker before winning a free-kick.

106' Underway! Porto get the second half in extra-time kicked off.
Despite Juventus having most of the ball in the first period of extra-time, Porto had the best opportunity to break the deadlock. Following a well-worked corner routine from the left, Marega failed to steer his close-range header either side of Szczesny. As such, there is still nothing between the two sides.

105' There will be two minutes of added time at the end of the first half in extra-time.

96' Sandro is caught in possession by Diaz on the halfway line, and the Brazilian opts to cynically bring down the attacker with a counter attack on the cards.

91' Kick off! Juventus get the first half of extra-time underway.
Following a dominant second-half display, Juventus take the tie to extra-time after overturning a two-goal deficit. After Oliveira’s spot-kick gave Porto the lead on 19 minutes, Chiesa pulled one back just a few minutes into the second half. Taremi was then dismissed for a second bookable offence, and Chiesa added his second just before the hour mark. The Old Lady pushed for a winner against 10-man Porto in the closing stages, but Morata had a goal ruled out for offside and Cuadrado struck the bar. Extra-time awaits.
90' + 7' FULL TIME: JUVENTUS 2-1 PORTO (3-3 ON AGGREGATE – EXTRA-TIME TO FOLLOW)

90' + 1' NO GOAL! OFFSIDE! Arthur lofts a dangerous throughball in behind for Morata, who neatly takes it down and finds the bottom-right corner via the post. The flag, however, is up for offside, and VAR confirms that the goal will not stand. Juventus thought that they had won it.
90' There will be five added minutes at the end of this second half.
89' With only minutes left to play, Juventus are pushing on in an effort to find a winner in normal time. Extra-time is looming.
87' Rabiot lines up an ambitious strike from range, and it sails over the top of Marchesin’s goal.
85' JUST WIDE! Marega uses his strength to hold off Demiral and turn onto his right foot from the left side of the hosts’ penalty area. After creating a yard of space, the striker fires inches wide of the near post. Szczesny looked beaten.
83' GOOD HIT! Sarr tries his luck from distance with a fierce left-footed strike, and Szczesny does well to parry it to safety from the centre of the goal.
82' VITAL SAVE! Juventus break down the left flank, and Chiesa easily skips beyond Corona and drives into the box. The winger sets himself on his right foot, but Marchesin is equal to his shot, before Morata slices the rebound.
80' Arthur looks for Chiesa’s forward run down the left-hand side of the field, although the flag is up for offside against the Italian.
78' GREAT CHANCE! Cuadrado once again whips a pinpoint cross in from the right, but Ronaldo gets it all wrong in the centre of the box as he heads the ball wide of the far post.
77' Juventus are camped inside the visitors’ half as they seek an all-important third goal. Following some patient play, Morata finds McKennie with a lofted throughball, and the substitute looks to head it back across goal for Ronaldo. Marchesin, however, is alert to the threat and gathers the headed pass.
73' If the score stays the same in the remaining minutes, the tie will go to extra-time. It is currently 3-3 on aggregate.
69' SMART STOP! After playing a short free-kick from the right, Rabiot fires a first-time shot towards goal, and Marchesin is equal to it at the near post.
67' Juventus are causing lots of problems for Porto in wide areas now. Sandro’s cross from the left just evades Ronaldo before falling for Rabiot, although the referee’s assistant has his flag up for offside against the Frenchman.
65' Chiesa is the first Italian to score twice in a Champions League match for Juventus since Alessandro Del Piero in November 2008.
60' Sandro opens up his body and fires a dangerous cross into the Porto box. The lofted pass just evades Ronaldo, and Pepe fires it away with Morata lurking.
58' Cuadrado switches over to the left and cuts onto his right foot looking for Ramsey at the far post with a cross. The delivery, however, just evades the Welshman and runs behind for a goal-kick.
56' OFF THE POST! Rabiot launches a well-weighted throughball in behind the Dragons’ defence for the overlapping Chiesa. The Italian rounds Marchesin, but, under pressure Pepe, the ball cannons against the post and out for a corner.
54' RED CARD! Taremi is sent off! After Marega was adjudged to have fouled Demiral while competing for an aerial ball, Taremi fires the ball forward after the whistle had gone. The Juventus players surround the referee, and he goes to his pocket to show the Porto striker a second yellow card.
52' GREAT CHANCE! Cuadrado finds space down the right to whip and in-swinging cross into the box, and Ramsey steers his header straight at Marchesin from the centre of the penalty area.
50' Mbemba catches Ronaldo, and Juventus win a free-kick down the left flank.
48' Porto had nine shots in the first half, their most in the opening 45 minutes of an away Champions League knockout game since April 2009. During that campaign, the registered 10 in the quarter-finals against Manchester United.
46' We are back underway! Kuipers, the referee, blows his whistle and Porto get the second half kicked off.
Despite dominating the ball, Pirlo will demand more from his side after the break. Although Morata missed a couple of clear-cut chances, the Old Lady have thus far failed to get Ronaldo into the game. If they hope to overturn the deficit in the second half, they will need to involve the Portuguese attacker at every opportunity. Conceicao, meanwhile, will be delighted with his team's first-half display. As they have done throughout this year’s competition, the Dragons look solid at the back and threatening on the counter.
Following an action-packed opening half, Porto take a one-goal lead on the night in at the break. In the opening stages, both sides had chances to take the lead with Taremi striking the bar and Marchesin keeping out Morata's powerful header. On the 19-minute mark, the Dragons broke the deadlock from the spot through Oliveira after a foul on Taremi from Demiral. Pirlo’s team responded well, and Marchesin was once again called into action to deny Morata’s close-range shot after he latched onto Cuadrado’s far-post cross.
45' + 4' HALF TIME: JUVENTUS 0-1 PORTO (1-3 ON AGGREGATE)
45' + 2' SAVE! Arthur brings down Manafa, and Porto win a free-kick in an advanced position down the right flank. Oliveira looks to drive a low delivery into the box, but it does not beat the first man. The hosts fail to clear the danger, and Oliveira’s shot from an acute angle is gathered by Szczesny.
45' There will be four minutes of added time at the end of the first half.
43' Oliveria sends a lofted throughball forward for Marega to chase, and Szczesny is quickly off his line to deal with the threat.
41' OPENING! Cuadrado’s resulting set-piece is flicked on in the centre of the box by Morata, and Marchesin is alert to beat Bonucci to the ball with the defender unmarked at the far post.
40' Cuadrado plays a corner short from the right, and the hosts eventually work the ball to Arthur. The midfielder goes for goal from range, and his strike cannons behind for another corner off Marega.
38' The Old Lady are enjoying their best spell of possession at present. However, Porto are lining up with a back six without the ball, which Juventus are struggling to break down.
36' Porto have had eight shots in the opening 36 minutes of play against Juventus, as many they had in the entire first leg.
34' Following that earlier knock, Pepe is now back to his feet and able to continue.

30' Sandro’s cross from the left is nodded out by Pepe, and Rabiot fires an audacious volley towards goal from a long way out. The Frenchman does not hit the ball cleanly, and it bounces through for Marchesin to make a routine stop.
29' Sanusi looks to chase a loose ball down the left flank, but just catches Rabiot’s ankles. The home side are awarded a free-kick.
27' WHAT A CHANCE! Cuadrado cuts inside onto his left foot and floats an inviting cross in towards the far post. Mbemba misjudges the flight of the ball, allowing Morata to take it down. From close range, the Spaniard looks to bend his strike beyond Marchesin, but the Porto goalkeeper parries the shot behind for a corner.
25' SMART STOP! Otavio tries his luck from the edge of the box, and his curling right-footed effort is gathered by the Juventus goalkeeper, who was quickly down to his left.
24' GOOD SAVE! The away side once again attack at pace on the counter. The Dragons this time drive forward down the right, and Corana sees a well-struck shot saved by Szczesny at the near post.
23' Cuadrado easily loses the ball to Otavio, and Porto launch a quick counter through Oliveria. The goalscorer drives forward before looking for Marega with a low left-footed cross, but Demiral reads the danger and clears.
21' Following that opening goal, Porto now lead the tie 3-1 on aggregate. As such, Juventus need to score twice to send the clash to extra-time.
17' PENALTY! Corana slides the ball down the right side of the hosts’ penalty area for Marega, who quickly steers it inside for Taremi. The striker shields it from Demiral, who catches him from behind and the referee points to the spot! After checking with VAR, the decision stands. Oliveira will take it...
16' Cuadrado looks to pick out Morata with a looping pass towards the edge of the area, but the throughball is overhit and runs through for Marchesin to claim.
14' Sanusi slips away from Ramsey and looks to slide Marega in behind the hosts’ defence, although the striker does not read the situation and Szczesny comes out to claim the ball.
12' Otavio pulls Cuadrado to the ground down the right flank and the decision goes Juventus’ way. Free-kick.

7' OFF THE BAR! Sanusi does brilliantly to skip beyond Cuadrado and drive into space in an advanced position down the left, before picking out Taremi in the middle of the area. The striker’s initial shot is blocked by Bonucci, and his follow-up effort is headed against the ball and out for a goal-kick.
5' Bonucci and Szczesny fail to deal with a pass in behind, and Marega almost goes through on goal, but his touch takes it over the line for a goal-kick.
3' GREAT CHANCE! Cuadrado finds space down the right-hand side of the field and whips a curling cross into the Porto box from deep. Morata peels into space and heads the ball towards goal, but Marchesin reacts quickly to deny the Spaniard.
2' WIDE! After some bright play, a loose ball falls to Uribe on the edge of the box, and the midfielder pulls his shot wide of the near post. Juventus did not close him down.
1' Sandro immediately looks to get Juventus on the front foot, but his forward pass catches Chiesa in an offside position.
1' Kick off! The referee, Bjorn Kuipers, blows his whistle and Juventus get the game underway.
The teams are out, and kick-off will soon be upon us here at Allianz Stadium.

However, the visitors Porto have been eliminated in each of their last three Champions League knockout ties after winning the first leg.
Following their two-goal Serie A victory over Lazio, Andrea Pirlo makes three changes to his starting side. Bonucci comes into the defence in place of Bernardeschi, Arthur replaces the suspended Danilo, and Ronaldo starts ahead of Kulusevski.
