The giant scoreboard at Old Trafford read "Chelsea 2-1 Manchester United" at full time.
Chelsea Manager Anelotti's pre-match interview must have been ringing in Sir Alex Ferguson's ear after the match. Ancelotti had told that he wanted to "hurt" Ferguson and his Red Devils at Old Trafford.
Ancelotti's wish came true as a superb Joe Cole goal and an equally controversial goal from Drogba secured three points for the Blues, leaving Ferguson and his men really hurt.
Many will agree that United's challenge for a record fourth consecutive league title is all but over after the Red Devils lost to a disciplined Chelsea team who played as was asked of them.
Ferguson's wish of winning United's record 19th league title may well remain a dream until next season.
Chelsea started the game against Manchester United at Old Trafford with their talisman striker Drogba on the bench. It was a bit of a gamble by Ancelotti, as he brought on Deco and Joe Cole in the midfield.
It paid off when Joe Cole superbly finished a hard-toiled opportunity created by "Man of the Match" Malouda in the 20th minute to give Chelsea the lead.
After halftime, United were the team in command despite Berbatov not being much of a problem for Terry and Alex. Zhirkov and Ferreira did a good job in containing United's attacks.
The match again proved United's dependence on Rooney for scoring goals. United did create a lot of chances in the second half, when they were completely dominating the pitch.
Rooney's absence in front of the goal was being felt, though, as Berbatov & Co. were short of ideas and stamina.
Ferguson should be very worried, for United face a full-strength Bayern in their return leg at Old Trafford on Wednesday. United are trailing the Bavarians 2-1 from the first leg.
Rooney's injury could not come at a worse time. Although he is expected to be back within a couple of weeks, United's European dreams could well be over by that time.
Coming back to the game at Old Trafford, Ferguson and his men can claim that bad refereeing cost them the match—and maybe the title—yet they cannot deny Chelsea were clearly the deserved winner.
Chelsea were in complete possession in the first half which saw them create numerous chances.
Except the 15-20 minutes late in the second half, when United pushed them to the wall, Chelsea dominated the game; disciplined defending from Chelsea's back four and Mikel saw United unable to create many moves into the Chelsea box.
An incisive pass from Kalou allowed Drogba to score Chelsea's second goal and his 25th league goal of the season.
Although United's super-sub Macheda scored within two minutes after entering the match, Chelsea did enough to see them take home those valuable three points.
With their second win against United this season Chelsea reclaimed their spot as league leaders, going ahead by two points over the Red Devils. Chelsea look to have got over their Champions League disappointment.
If Ancelotti's men maintain the momentum they can very well land England football's most coveted trophy after a gap of four long years.
The win against United was morale-boosting and equally satisfying. After today's game, the Blues' quest for a "DOUBLE" looks a bright possibility. That should be a huge boost to the players, manager, owner and the fans alike.
