Barcelona will try to recover from the 3-0 victory at the Juventus Stadium in a feat that seems improbable to say the least. The Italian side are strong defensively and dangerous in attack, which will make things harder for Enrique's side to repeat the heroics displayed against PSG.
Busquets is back for the home side after his first-leg suspension, while Juventus star Dybala is finally fit for the fixture after suffering a slight injury at the weekend. Barcelona need to score at least three goals tonight in order to force the game into extra time, against a Juventus side who have conceded two goals in the Champions League this season.
