Didier Drogba has told his Chelsea team-mates they must play like champions against Manchester United tomorrow to keep their title hopes alive.

Chelsea will draw level with Sir Alex Ferguson's men with just two games to go if they pick up all three points at Stamford Bridge, although would still trail on goal difference.

Drogba is still cursing his knee injury which forced him to miss the match against Wigan 11 days ago, when Emile Heskey's late equaliser prevented Chelsea from now having their championship chances in their own hands.

But the Ivory Coast international, who returned against Liverpool in midweek, is feeling the benefits of his rest and is determined to make United pay.

He said: "We need to play like champions. There is no more to say. I want tomorrow to come quickly and be on the pitch. I enjoy these kind of games.

"I had to leave my friends when I wanted to help them against Wigan and maybe the League would now be a different story, but we're still on for it.

"My knee is improving. It was good for me to rest for a few days because it wasn't getting better. I'm a little bit fresh after that 10-day rest and I feel good for sure."

Goalkeeper Petr Cech believes Manchester United will struggle to cope with the pressure should Chelsea join them at the top of the League, despite only having games against West Ham and Wigan to clinch the title.

He said: "If we beat them it won't be enough for us, but hopefully we can put them under pressure. They still have two to play and it's always difficult to win."

Chelsea will have to beat United without midfielder Frank Lampard, who is on compassionate leave due to the sad loss of his mother, but they are now back to their full quota of goalkeepers after Carlo Cudicini declared his fitness following a hamstring injury.

Manager Avram Grant was facing the prospect of bringing an emergency keeper on loan just a few weeks ago when Cech sustained a facial injury and No2 Cudicini limped off against Fenerbahce.

But both have made rapid recoveries with Cech having played the last three games, while Cudicini returned to training this week.
