Kevin-Prince Boateng is convinced AC Milan can upset Barcelona in their Champions League clash.

Both teams drew 2-2 in their domestic games on Saturday evening, as Barça threw away a 2-0 lead against Real Sociedad, while the Rossoneri fought back from 2-0 down to hold Lazio.

They go head-to-head at the Nou Camp in the opening Champions League match on Tuesday night.

"If I thought we couldn't win, then I wouldn't be playing football. I dreamed of a game like this since I was a kid. Nobody is unbeatable," smiled Boateng in the Gazzetta dello Sport.

"We have to stay solid and united, because we're on their turf and must defend well. In attack we have exceptional strikers and sooner or later we will score. I think it'll end 1-1.

"If we don't give Xavi and Andres Iniesta time to think, then it becomes very difficult for them to find the net. Those two are the right and left side of the Barcelona brain. Without the brain, teams cannot play.

"Who is Milan's brain? Zlatan Ibrahimovic. Zlatan drags us all forward and is very important for us."
