Mikel John Obi was the latest casualty after limping off the field against Everton on Sunday, adding to those undergoing treatment -- Andriy Shevchenko, Michael Ballack, Ricardo Carvalho and Arjen Robben are undergoing treatment, while Ashley Cole is facing a race against time to be fit.

Mourinho could have just 15 senior players fit for the May 19 Wembley showpiece.

"If Ashley is ready we have 15 players for the final," Mourinho told Chelsea TV. "I will have to choose between Hilario because he is not bad playing forward, or I'll bring one of the kids to make 16."

Michael Essien and Claude Makelele were rested against Everton on the final day of the Premiership season, with Mourinho using youngsters Sam Hutchinson, Ben Sahar and Nuno Morais off the bench.

Mikel picked up a muscle injury in the 1-1 draw and limped off with 16 minutes remaining. "We will see but I think he is out of the game," said Mourinho.

Chelsea have recorded one win since April 18 and that was the Champions League semi-final, first leg against Liverpool which was cancelled out at Anfield.

Jose Mourinho's men have also seen the Premiership title go to Manchester United, who they face at the new Wembley Stadium on Saturday.

Keeping pace with United has not been helped by the injuries in Mourinho's squad which may lead to goalkeepers Hilario and Carlo Cudicini being on the bench for the final game of their season.

Victory for Chelsea's depleted squad at the weekend would put a smile back on the face of John Terry, who is determined to be the first skipper to lift the FA Cup at the new national stadium.

"I have not been too happy recently but that is the same for all the lads and it is good to see," he said. "The last thing I would have wanted was to get knocked out of the Champions League, lose the Premiership and be happy, and it has been nice to see everyone moping about a bit."

After conceding their Premiership crown, Terry and his team-mates then gave United a respectful guard of honour at Stamford Bridge when they clapped the new champions on to the pitch.

Terry added on club website chelseafc.com: "I certainly didn't like it. As I'm sure they didn't like it two years ago. But it is part and parcel of the game and we both showed respect."

However, Terry wants to pick up his players for the club's first FA Cup since 2000.

"This is a competition we as a team haven't won yet, like the League Cup two years ago when it was a first chance to win a trophy together," he added. "It is a great trophy and the first one at the new Wembley. That is another reason to be fired up.

"It is like not having won the Champions League together. If we can keep building on things like winning the FA Cup, hopefully next year the Champions League might come."
