Robben a doubt for Blues

Chelsea winger Arjen Robben is a doubt for Sunday’s game at Manchester United with a muscular problem, but full-back Asier del Horno could be fit to start.

Robben came off during the midweek defeat by Real Betis, while del Horno missed the game completely but has since recovered from a knock.

Hernan Crespo did not travel to Spain but has since returned to training and faces a fitness test, while Glen Johnson is definitely out after having surgery on a hand injury.

Provisional squad: Cech, Cudicini, Ferreira, Gallas, Carvalho, Terry, Huth, del Horno, Bridge, Makelele, Essien, Lampard, J Cole, Geremi, Wright-Phillips, Duff, Robben, Gudjohnsen, Drogba, Crespo, C Cole.
