FC Barcelona will have to deliver a spectacular performance at Camp Nou after losing 2-0 on the road Wednesday in the first leg of its Champions League elimination battle with AC Milan.

Barça, which has been nearly unbeatable in all competitions this season, dominated the ball in the first half, yet the home side allowed their highly favored opponents only a handful of genuine chances.

AC Milan grabbed the lead in the 57th minute, when Kevin-Prince Boateng connected after teammate Cristian Zapata appeared to touch the ball with his hands.

Barcelona's vociferous protested gained them nothing but a yellow card for defender Gerard Pique.

Leo Messi had a chance to bring Barça even, but his free kick sailed over the Milan goal, while Andres Iniesta's long shot in the 76th minute passed inches outside the post.

It was just a few minutes later when Muntari put the game out of reach, delighting the 80,000-strong home crowd.

In Istanbul, German club Schalke managed to pull out a 1-1 draw against a Galatasaray that recently added Didier Drogba and Wesley Sneijder to an already formidable lineup.

Burak Yilmaz scored for the home side at the 12-minute mark and U.S. international Jermaine Jones got the equalizer in the waning moments of the first half. EFE
