For a moment, it appeared that Chelsea was right back in contention to advance to the semi-finals of the Champions League.
But that's about exactly how long it took for the Blues to return to being out of contention: a moment.
Down a goal, forward Didier Drogba broke out of his scoring slump, and found the back of the net on a breakaway goal after a fine feed from Michael Essien in the 77th minute.
But right after the goal, Wayne Rooney led Ryan Giggs, who picked up his second assist of the match when he found Ji-Sung Park who chested the ball and hammered a shot by Petr Cech.
Manchester United just had to avoid making any glaring mistakes, which they did, and held off their Premier League foes, 2-1, and 3-1 on aggregate, to advance to the semi-finals.
The goal by Park was a demoralizing play for Chelsea, who were playing a man down after Ramires picked up his second yellow card in the 69th minute.
Manchester United got a late score on Chelsea before halftime as the Red Devils jumped to a 2-0 aggregate score.
Thanks to a well-placed cross by Giggs, Javier Hernandez was able to knock in a goal in the 43rd minute.
Chelsea players protested that Hernandez was offsides, but on replay the goal appeared to be the right call.
Chelsea had a great chance in the 29th minute when Edwin van der Sar got caught outside the box. But the tall Dutch goalkeeper was able to recover by out-smarting Nicolas Anelka by dispossessing him, and then clearing it out of bounds.
It's a great night for the Red Devils as they will likely face Schalke in the semi-finals.
For Chelsea, this might mean the end of the Carlo Ancelotti era.
