Fonseca said: "If we have more want to score or not concede a goal? Both (laughs). This is a very dangerous match against a very, very strong team. We have to understand the game and play balanced. But we know that when you play a match against a team like Aston Villa you can't make mistakes. We have to be confident and choose the right moment to take more risks. We have to be careful.
"They are very, very strong. We need to understand how they play. The match against Arsenal was a magnificent example. They defend very well and wait for the moment to counterattack. They have no problem always defending, they wait for the right moments to be very dangerous on the counterattack. We have to be careful in this phase of the game: we face a team with a very strong defensive organisation, one of the best I've seen in the main championships.
"I expect to face a team with a similar game plan to the one we followed against Arsenal.
"I think we have shown that we can adapt to any match. It will be difficult tactically, but we have prepared well. We know Aston Villa well and Aston Villa know us too. We prepared the match to have the chance to win it. we prepared like the first match, which was a good match, not to defend it. We dominated.
"We wanted opportunities to score against a team that defends very, very well."
