The Uruguayan said: "I don't think we are favourites, we did a good job here, we won the game and they didn't score, but they are a strong team with good players and we know it's going to be a difficult game.
"We've played there before in the Champions League and in a friendly game, so we know how it's going to be. It's going to be a tough game. We know they are very strong there. We will have to play intelligently.
"But the team is prepared and we have to focus on events on the pitch and not on what's off it."
