Inter Milan dealt a huge blow to Barcelona's Champions League ambitions as they were victorious in the first leg of the semi-final by three goals to one.

Barcelona looked to be in control from the early stages as they dictated the tempo in midfield. However, it was clear from the very start of the game that Inter were picking holes in the Barcelona defense leaving them badly exposed.

Barcelona's early endeavour was rewarded by a goal from this year's star youngster, Pedro. Maxwell made a superb run down the flank and cut the ball across goal to Pedro who finished first time in style.

Inter were quick to respond. Some terrific play from man-of-the-match Diego Milito set up Wesley Sneijder, who stroked the ball into Valdes' near post on the half an hour mark.

Barcelona would be undone twice more after the break. Maicon scored the first after a strong run and tap in, while Diego Milito headed in the 3rd after it looked like he was in an offside position.

Lionel Messi was neat in possession, but again, had little opportunity to shine. He could not find a way through a tough Inter defense.

The next leg will be played at the Camp Nou next Wednesday where Barcelona will need a huge performance. They will be without defender Carles Puyol who picked up a yellow card today.
