Stamford Bridge Stadium has been a tough pitch for Manchester United, but the history chaged last night. Ferguson's team defeated Chelsea 0-1 with a great goal scored by Wayne Rooney.
This quarterfinal duel is not decided yet, but United took one step of advantage with this result. Rooney's goal - which came after a superb move of Ryan Giggs - can be a crucial factor in the end.
Chelsea almost score the equalizer when Fernando Torres blasted his shot close to the post, but Van der Sar stopped the ball.
Alex Ferguson said that "nothing is decided yet, but this victory is really important". The ticket for the semifinals will be decided on April 12, at the Old Trafford Stadium.
