London, April 5:

AS Roma earned a 2-1 win over 10-man Manchester United and Valencia held host Chelsea to a 1-1 draw during their first leg of the Champions League quarter-final matches on Wednesday.

Roma got goals from Rodrigo Taddei and Mirko Vucinic, where Man United fans fought briefly with police after the first goal. Didier Drogba scored the equalizer for Chelsea, the two-time defending English champion which has never won the European Cup.

Taddei scored from inside the area in the 44th minute, sending a low shot from 12 yards past goalkeeper Edwin van der Sar after a deflection off Man United defender Wes Brown.

After the goal, opposing fans taunted each other by banging on the partition separating the sections. One fan was seen lying with blood covering his face as police hit fans with night sticks to restore order. There was also violence before the match, with several United fans injured in clashes outside the stadium.

Wayne Rooney equalized for United in the 60th, chesting down a cross from Ole Gunnar Solksjaer and easily shooting past Roma goalkeeper Alexander Doni. The goal was Rooney’s first in the Champions League since he scored three in his debut against Fenerbahce in September 2004.

But Vucinic put Roma ahead again in the 66th, putting in a rebound after Mancini’s hard shot was stopped by Van der Sar. United played with 10 men after midfielder Paul Scholes received his second yellow card in the 34th for taking down Totti.

Roma is playing in the quarter-finals for the first time since the tournament was renamed the Champions League in 1992. The last time the Italian team advanced to the last eight of the European Cup in 1984 when it reached the final.

Drogba equalized for Chelsea with a header in the 53rd minute after a long, looping pass from Ashley Cole. Valencia goalkeeper Santiago Canizares sent a goal kick straight at Cole, who controlled the ball and sent it right back toward the Valencia box. The ball bounced once and Drogba got to it before Valencia defender Roberto Ayala.

David Silva had provided Valencia the lead in the 30th, taking a throw in on the left and dribbling toward the middle before unleashing a hard, 25-yard shot that left Chelsea goalkeeper Petr Cech no chance.
