Allegri expects a tight affair - especially in the early exchanges.
"It will be a competitive game of great intensity, where both sides will show their defensive strength. We'll have to repeat the performance we gave at the weekend in the championship versus Siena.
"Winning always matters to us, but I look to be a realist. We are working hard to improve, but I can't expect my side to dominate a game for 90 minutes.
"The semi-final is an objective, but it will be hard as we are going to play on one of the most difficult grounds that there are. It's a shame that this is only a quarter-final tie.
"Juventus are the strongest and most solid team in Serie A. They collected 44 points in the first half of the season, there is not too much more to say. It is excessive to look for negatives in this Juventus."
