Atletico Madrid president Enrique Cerezo admits the San Siro crowd could be a factor tonight at AC Milan.

Atletico are in Milan for their second Champions League group game.

Cerezo said today: "It is a very complicated group and we know that we need to win to move on to the next phase. The team is in very well and we are going with the idea of taking the three points.

"The players know the responsibility that this match entails.

"The coach (Diego Simeone) is calm and hopefully all the players can connect to the team's system of play. The stadium may have 75 percent occupancy and this is good news. Hopefully we can see a good match."
