46' We're back underway at Allianz Stadium.
Andrea Pirlo will be concerned by his side's performance in the first half. They were lacklustre in the final third, even though Morata did have the ball in the net twice. The Spaniard has been off the pace, being caught offside twice. Paulo Dybala has also been largely ineffectual. The Bianconeri need more from the two players in the second half.
Barcelona lead Juventus 1-0 at the break in their Champions League clash at Allianz Stadium. Ousmane Dembele put Ronald Koeman's men in front courtesy of a deflected strike from the edge of the box. Barca should arguably be out of sight, but Lionel Messi, Dembele and Antoine Griezmann failed to convert further openings. Alvaro Morata has had two goals disallowed for the hosts, who have been underwhelming in the final third.

17' The referee has a word with Alba following a strong challenge on Cuadrado on the right flank.
16' VAR! The referee doubles checks the Morata decision with VAR. It proves that there was both offside and handball infringements. It didn't have much going for it.

1' We're underway at Allianz Stadium.
This will be the 14th match between Juventus and Barcelona in competitive football, with the Italian giants failing to score in their last three meetings with the Spanish outfit (D2 L1).
Barcelona also have a slew of injuries to contend along with Gerard Pique's suspension. Marc-Andre ter Stegen, Samuel Umtiti and Philippe Coutinho are all injured, resulting in Neto starting once again between the sticks. Araujo gets the nod to start in the backline in place of Pique. Busquets, Dest and Fati all drop to the bench from the side that was beaten by Real Madrid. Griezmann, Dembele, Sergi Roberto and Pjanic are all inserted into the line-up.
Juventus are still without Cristiano Ronaldo after the Portuguese returned a second positive coronavirus test. The Bianconeri are also without defenders Giorgio Chiellini and Matthijs de Ligt, although Dybala and Bonucci are available for Pirlo. There are three changes from their side that drew 1-1 against Hellas Verona as Ramsey, Arthur and Bernadeschi drop to the bench and Bentancur, Kulusevski and Chiesa start.
BARCELONA SUBS: Sergino Dest, Sergio Busquets, Carles Alena, Martin Braithwaite, Riqui Puig, Trincao, Ansu Fati, Junior Firpo, Inaki Pena, Arnau Tenas.
BARCELONA (4-2-3-1): Neto, Sergi Roberto, Ronald Araujo, Clement Lenglet, Jordi Alba; Frenkie de Jong, Miralem Pjanic; Pedri, Lionel Messi, Ousmane Dembele; Antoine Griezmann.
JUVENTUS SUBS: Arthur, Aaron Ramsey, Weston McKennie, Carlo Pinsoglio, Federico Bernardeschi, Koni de Winter, Gianluca Frabotta, Manolo Portanova, Alessandrio Pio Riccio, Gianluigi Buffon.

Barcelona have endured a torrid week, suffering a 3-1 defeat at the hands of Real Madrid in El Clasico. They were soundly beaten by their rivals at Camp Nou before club president Josip Maria Bartomeu announced his resignation along with other members of the board. It has left the Catalan side in bizarre position off the field, but Ronald Koeman has to put that to one side to help his team get back to winning ways.
Juventus defeated Dynamo Kiev in their opener by a 2-0 scoreline to kick off their Champions League campaign on the front foot. Maurizio Sarri was sacked after their defeat to Lyon last season, therefore it was crucial for Andrea Pirlo to begin a victory. The Bianconeri earned the three points courtesy of a brace from Alvaro Morata to match Barca's start in Group G, but they face a challenge tonight against the Spanish outfit.
Good evening and welcome to the live commentary of the Champions League clash between Juventus and Barcelona at Allianz Stadium.
