90'+3'   FT. Barcelona qualify for the knockout stage of the Champions League. Sporting's 3-1 defeat of Olympiacos means Juventus are yet to proceed. 

90'+2'   Big, big save from Ter Stegen to prevent Dybala scoring a late winner. The Juventus No.10 bends a low, first-time shot to the far corner. The German flings himself to his right and tips the ball around the post. Barça deal with the subsequent corner. 

90'+1' Piqué takes his place in the book for a tackle on Dybala. 

90'   Three minutes of added time. 

90'   Barzagli tries to steam past Umtiti on the left. At 36, that was a touch ambitious and the Frenchman gathers the ball. 

87' Lucas Digne sees his name scribbled in the referee's book after he grabs a load of Dybala's shirt. 

85' And that will be Costa's final contribution. He's replaced by Matuidi. 

83'   Douglas Costa twitches inside from the left and drags a shot wide of the upright. 

81' Barça swap: Iniesta goes off to a standing ovation from the Juventus fans. Jordi Alba is on in his place. 

79'   The home side are slowly turning the screw as the match nears its final 10 minutes. Black-and-white shirts are camped inside the Barça half. Oh, hang on, Sandro cleans out Suárez and Barcelona will be able to relieve the pressure. 

75'   Juventus are unlucky not to have a penalty after Piqué catches Douglas Costa's heel just inside the box. 

72' Semedo draws Alex Sandro in to a foul on the edge of the box. It was a fine first touch that deceived the Brazilian. Messi fizzes in a cross that is cleared at the near post. 

71' Another change for Juve: Claudio Marchisio replaces Cuadrado. 

68'   Lucas Digne appears to have a strong aversion to shooting. The left-back finds himself inside the box with a good chance to shoot. Instead of doing so, he tries to thread the ball to Suárez at the far post, and it's intercepted. 

66' Miralem Pjanic, who was on a yellow card, is replaced by Rodrigo Bentancur. The Uruguayan youngster joined from Boca Juniors earlier this year. 

64'   Ooof, Messi curls it towards the near top-corner and the ball whistles over the bar. Buffon probably had it covered, in any case. 

63'   Benatia protests, but the referee penalises him for a late lunge on Suárez. Barça have a free-kick just outside the box. And this time, Messi is on the pitch. 

61'   Higuaín, who has been quiet this evening, turns and shoots on the edge of the box. Umtiti stayed tight to him, and that pressure caused the Argentine to spray the ball well over. 

58'   Dybala tees the ball up for himseld and lets fly on the edge of the box. It deflects behind for a corner, which Barça clear. There has still yet to be a clear-cut chance in this match. 

55' Suárez goes down grasping his face after very light contact from Benatia. That stoppage gives Valverde the opportunity to make his first change. Lionel Messi comes on for Deulofeu. 

54'   It's nearly Messi time... he's kitted up in the dugout. 

52'   Deulofeu roars away from Alex Sandro with a spectacular burst of pace, before fizzing the ball in to the six-yard box. Benatia clears, falling backwards as he does so. 

50'   Oooh! Suárez' shot skids off the top of the wall and behind for a corner. Juve clear, but Barça continue in possession.

49'   Khedira grabs Iniesta's shirt on the edge of the box, and Barça have a free-kick in a dangerous position. Suárez stands over the ball, eyeing up his angles. 

48'   Umtiti makes an important interception to prevent the ball running through to Cuadrado, who was running through on goal behind him.

46'   Messi is waltzing up and down the touchline on his warm-up. 

46' Barça get the second half underway! 

Juventus and Barcelona amble in to the dressing rooms at 0-0. The visitors came closest to breaking the deadlock when Ivan Rakitic's free-kick went all the way through a crowd of players and bounced off the post. 

45'+1' HT. 

44'   Dybalaaaa... Over! The Argentine picks up the ball on the edge of the box and dances around the outside of the Barça defence. By the time he has a clear line of sight at goal, the angle is tight. His only chance is to blast the ball at goal, and he gets under it a little too much. 

43'   Gerard Deulofeu creates enough space to fashion a shot from just inside the box. It's a nicely-shaped curler, but fairly easy for Buffon to scoop up. Deulofeu has had a strong first half. He's playing off the right, but with Semedo outside him, he has plenty of opportunity to drift inside. 

37'   Juan Cuadrado volleys the ball over the bar and half way to Barcelona. The Colombian did well to fashion a chance at all, in his defence. He scooped the ball up to Dybala, who headed it back to him. Fine 'headers and volleys' play there. 

35'   Good work from Semedo on the right. He draws Alex Sandro in to making a challenge, only to dance around him and dink the ball in to the centre. The cross went to a dangerous area, but Khedira is well-positioned to head clear. 

32'   Lucas Digne and Samuel Umtiti clash, and both rise up gingerly after receiving treatment. Digne slid on the ground, holding his head after a coming together with Cuadrado, and took out Umtiti in the process. Given that Piqué is suspended for the big LaLiga match against Valencia on Sunday, it will come as a serious blow if Umtiti cannot continue. 

30' Paulinho is booked for diving. The Brazilian chips the ball past Pjanic and then collapses to the floor.

24'   Deulofeu works back and tries to prevent Alex Sandro swinging in a cross. It becomes clear that Deulofeu is not a defender by trade when he is utterly bamboozled by Sandro's step-over, and hacks him down. Pjanic delivers a free-kick to the near post and it comes to nothing. 

22'   Barcelona hit the post! Paulinho and Busquets hurl themselves towards Rakitic's enticing delivery from the free-kick. Both miss, and the ball bounces up on to the post. Paulinho gets his head on the rebound, but can't react quickly enough to direct it at goal. 

21' Iniesta robs the ball off Dybala and bursts forward. Pjanic is having absolutely none of that, and scythes the Spaniard down. 

18'   Rakitic and Umtiti exchange shrugs and gesticulation. The pair conspired to lose the ball in the box, presenting Dybala with a chance to shoot. Ter Stegen, as has been the case so often this season, keeps the opposition at bay.

17'   Iniesta reads Cuadrado's wild headed backpass to Buffon, but by the time Barça's No.8 can get to the ball, the angle is acute. He catches the ball on his left foot and it flies over. 

16'   Gerard Deulofeu shows neat footwork to get to the byline, but his cut-back fails to find Suárez. 

14'   Dybala pirouettes delightfully in the centre to escape Busquets, before playing the ball to Cuadrado on the right. His cross is behind Higuaín, but Douglas Costa scampers out wide to recover the ball and send in another cross. Lucas Digne, filling in for Jordi Alba at right-back, clears this one with a firm side foot. 

12'   Two shots for Barcelona so far. Both by Paulinho. 

10'   Paulinho plays a neat ball 'around the corner' to Suárez with the outside of his boot, before then collecting the ball off the Uruguayan and shooting. His shot is somewhat less slick than his contribution to the build-up, and it dribbles wide. 

8'   Miralem Pjanic looks up with a rather bemused look on his face. The outstretched arm of Paulinho reaches down to help him up, which is amusing, given that Paulinho's relentless hacking resulted in him being sat on the deck in the first place. 

5'   Piqué plants his foot in the path of a fizzing low cross from Douglas Costa. With Gonzalo Higuaín lurking in the six-yard box, that was an important intervention. 

4'   Juventus are dominating possession in the early stages. That's the new-look Barça under Valverde... far more happy to concede possession than in previous seasons. 

2'   Douglas Costa is at the start and the end of Juventus' first attacking move. The winger glides past Samuel Umtiti before laying the ball off to Cuadrado on the right. A couple of step-overs later, Costa has the ball back at his feet inside the box. He shoots low, and Ter Stegen gets down well to gather. 

1' Peeep! Paolo Dybala kicks off for Juventus and we're up and running. 

Here come the teams! The Juventus fans are holding up a vast 'tifo' with Mario Mandzukic's face on it. The Croatian isn't in the starting line-up for Juve today. 

Lionel Messi and Ernesto Valverde agreed several days ago that the Argentine would sit out tonight's match. Here is the full story. 

  The Barcelona team have just trotted out for their warm-up in Turin, sporting rather garish 90s-goalkeeper-style sweaters in pink and navy blue. 

Barcelona face a top-of-the-table clash with Valencia on Sunday. A victory for Barça would open a seven-point gap at the top of the table over Marcelino's resurgent side. Within that context, Messi's place on the bench becomes easier to understand. 

We are also bringing you live coverage of PSG vs Celtic this evening. William is manning the keyboard for the clash in Paris. 

Gianluigi Buffon is back between the sticks for Juve after recovering from his World Cup heart-break with Italy. He missed the Serie A clash with Sampdoria at the weekend.

  Juventus XI: Buffon; Barzagli, Benatia, Rugani, Alex Sandro; Pjanic, Khedira; Cuadrado, Dybala, Costa; Higuaín.

Lionel Messi is on the bench for Barcelona. With Barça three points ahead of Juventus at the top Group D, Ernesto Valverde has ostensibly taken the opportunity to rest his star player. 

Barça XI: Ter Stegen; Semedo, Piqué, Umtiti, Digne; Paulinho, Rakitic, Busquets, Iniesta; Deulofeu, Suárez.

Juventus have not lost at home in the Champions League for over four years -- a 21-match unbeaten streak. That last loss, which is also their only Champions League defeat in their current stadium, was inflicted by Bayern Munich in the 2012-13 quarter-final second leg, by a scoreline of 0-2. 

Luis Súarez has yet to score in the Champions League this season. He has looked sluggish for a couple of months. But a double against Leganés at the weekend could invigorate the Uruguayan. 

Juventus coach Max Allegri is concerned by Juventus' recent habit of leaking goals: "We're lacking defensive intensity. We're scoring goals, but conceding a lot. You have to find a balance." 

Ernesto Valverde will be praying that nothing happens to Samuel Umtiti and, if he features, Thomas Vermaelen this evening after Gerard Piqué had his one-match ban upheld by the RFEF on Tuesday, ruling him out of the top of the table clash at Valencia on Sunday.

Juve and Barça captains Gianluigi Buffon and Andrés Iniesta gave an interview in the run-up to the game in which they discussed the inevitability of retirement.

Leo Messi will be keen to add to his brace from the reverse fixture in Camp Nou, but the Argentinean has failed to score away from home in Europe in over a year.

Juventus and Barcelona go head to head in Turin this evening in a game that will go some way to determining who tops the group when the dust settles. Barça are in the driving seat with 10 points to Juve's seven and a draw will be enough to see Ernesto Valverde's side through to the knock-out stages. A Juve win will see everything go down to the wire in the final round of fixtures.
