Down by three points in the Premier League standings, Chelsea need to beat Manchester United at Old Trafford.

With only two matches to follow for each club, this really is the deciding match of the season.

Chelsea need a big match from Didier Drogba, because they likely won't get much out of Fernando Torres. Nicolas Anelka hasn't scored since February, so Drogba will be the key for Chelsea.

Drogba needs to get touches, and it will be up to Frank Lampard, John Mikel Obi, and Michael Essien to make it happen. Though Drogba's performance is vital to Chelsea's success, so is getting him the ball to score or create opportunities.

Not only is Drogba playing to win Chelsea a title, but he has personal incentive to find the back of the net. His goal scoring has declined this season, and the signing of Torres had to have been an insult. A big match from Drogba can silence doubters who think the striker's best days are behind him.

The job of containing Drogba will mainly fall upon Nemanja Vidic. The Serbian central defender is among the best players in the Premier League, and his skills will be tested on Sunday. He's hard-nosed and very good in the air, two qualities that might be very important on Sunday.

Should Vidic frustrate Drogba this weekend, Chelsea will be in deep trouble. The Blues needs to get on the board, and Drogba offers their best chance to do it.

Manchester United will look to Wayne Rooney to provide goal-scoring opportunities. After resting this week in the Champions League semi-final, having sat out two matches for suspension, and having a fully healed hamstring, Rooney should be in good shape.

Chelsea defender David Luiz, who is still a little raw, may have his hands full with Rooney, as well as Javier Hernandez. The young Mexican star has given defenses fits for his ability to weave through defenders.

The last time these two clubs met in a Premier League match, Chelsea came out ahead 2-1 at Stamford Bridge.

Expect revenge to be on the Red Devils' minds following that defeat, and a victory is certainly probable considering Manchester United have not lost a Premier League match at Old Trafford all season.

This match will be intense from start to finish. Manchester United recently lost to Arsenal, so a loss to Chelsea in their home stadium would be devastating.

Chelsea will be playing for a win, which means they will be in attack mode. With Manchester United in top form, the Blues need to be at their best.

PREDICTION: Chelsea will put up a valiant effort, and Drogba will contribute to a goal, but it won't be enough. Rooney, Ryan Giggs, and Nani will counter attack and beat Petr Cech in the second half.

SCORE PREDICTION: Manchester United 2, Chelsea 1.
