Desailly revealed to his website: "After a few days' rest at the start of last week, I have returned to London for treatment. It now feels much better. I will probably need another few days to get back on track and then, if everything goes well, I'll be ready for our game against Fulham."
The Blues need to win most of their remaining games if they are to get a Champions League place and they face crucial games in their run in against Manchester United and Liverpool. They also have a chance to exact revenge against Spurs in the FA Cup at the quarter final stage.
