Juventus manager Massimiliano Allegri has claimed that his side will need to score twice in order to progress from their Champions League last-16 tie with Borussia Dortmund.

The Bianconeri edged to a 2-1 victory in the first leg, but Allegri is well aware of the danger that Marco Reus's strike in Turin could pose.

"We start with a 2-1 advantage from the first leg," Allegri told reporters. "We know how difficult the game will be, but so do Borussia. We must do everything right, from every point of view. I hope it'll be a good game.

"It's unlikely to end 0-0, so we need two goals to go through. In the first leg we didn't allow them a shot on goal, and Borussia scored because [Giorgio] Chiellini slipped, while we had several chances to score.

"We have to know what Borussia's qualities are, they have great pace and pressing, we'll have to make very few mistakes tomorrow and hit them where they have weaknesses."

Juventus last won the Champions League in 1996.
