Juve face uphill battle after being held in Turin.
Juventus were held to a 1-1 draw by Italian rivals Fiorentina in Turin in a repeat of the 1990 UEFA Cup final.
Juve won that tie and also beat La Viola 1-0 in Serie A last weekend, and they opened the scoring on Thursday when Arturo Vidal fired home inside three minutes.
Antonio Conte’s side are hoping to go all the way to a final that will be played in their own stadium but Fiorentina are still very much in the tie after Mario Gomez levelled the scores on the night and grabbed a precious away goal in the 79th minute.
