PREDICTION

Chelsea are riding high after scoring 12 goals in their last two games, but will know they face a much more difficult task in overturning Manchester United at Old Trafford, having only beaten their hosts twice in the last ten league meetings between the two at the Theatre of Dreams.

United relinquished a lead against Bayern in midweek, but Sir Alex Ferguson's charges reversed the same deficit against Liverpool just two weeks ago and could open up a four-point gap at the top of the league.

Manchester United 2-1 Chelsea

April could prove to be the cruellest month, at least for Manchester United fans. The Red Devils could be without star man Wayne Rooney for three crucial weeks after he damaged ankle ligaments in Tuesday's Champions League loss at Bayern Munich.
Rooney now faces an anxious wait to see if United's pursuit of Premier League and Champions League glory falters in his absence.
While Sir Alex Ferguson has lost his biggest goal threat, the headache for Carlo Ancelotti is how to find room for both of his front-line strikers. Perversely, Chelsea have produced some of their best performances without leading scorer Didier Drogba. His absence allows Nicolas Anelka to play a more advanced role, which in turn gives Frank Lampard more space in midfield.
Drogba was not involved in either of the Blues' seven-goal victories this season (against Aston Villa and Sunderland). Chelsea also had few problems coping without him during the Africa Cup of Nations, winning all five of their league and cup games in January. But with 10 goals in his last eight league games, dropping Drogba is not an option.
Ancelotti may feel now is a good time to visit Old Trafford, scene of his win in the 2003 Champions League final with AC Milan. The Red Devils have lost three of the four league games that have followed European away games this season.
The Italian, who has won five of his last six meetings with Sir Alex Ferguson, says Rooney's injury is a boost to Chelsea's title hopes, but he knows better than most that United will fight to the finish. Ancelotti was the Juventus coach when the Red Devils famously clawed back a two-goal deficit in Turin to reach the 1999 Champions League final.
