Udinese came from behind to beat AC Milan 2-1 at the San Siro Stadium on Wednesday night in the quarter-finals of the Coppa Italia, handing Clarence Seedorf his first defeat since taking charge.

After knocking out Inter earlier in the competition, Udinese can claim the double Milan scalp by beating the Rossoneri to qualify for the semi-finals.

Milan got off to a flyer when Mario Balotelli tapped in Valter Birsa’s cross after a swift counter-attack.

Bruno Fernandes had a chance for Udinese on the half-hour mark, but his Cristian Zapata did well to  block his attempt from close range.

In the 38th minute Fernandes took advantage of some sloppy defending and tried a shot at Milan’s goal but it lacked power and Christian Abbiati saved easily.

Just before half-time Udinese were back in the game when Silvan Widmer was fouled in the box by Urby Emanuelson, and the referee awarded a penalty.

Luis Muriel took the spot kick and although Abbiati got a touch, the penalty shot went into the goal.

Udinese almost took the lead in the 59th minute, after some good inter-play between Muriel and Fernandez, the latter set up Andrea Lazzari, but his shot lacked power and Abbiati made the save.

But the visitors would grab the winning goal in the 79th minute, when Robinho was robbed of the ball in the Udinese half by substitute Nico Lopez.

Lopez sped into the Milan half and fired a shot into the bottom corner, a goal worthy of being the winner.
