Fernando Torres is set to miss Chelsea's Champions League clash with Schalke after limping out of training.

And the Blues' boss Jose Mourinho could be ready to make other changes, with Ashley Cole and Frank Lampard in danger of missing out.

Torres pulled up with a muscle problem halfway through Monday's session at Cobham and withdrew to receive treatment.

The in-form Spanish striker is understood to have been initially concerned about the scale of the problem, which was assessed by club medics.

He is keen to stay as first choice for Mourinho's side after getting off the Premier League mark with the last-gasp winner over Manchester City a week ago, which followed his double in the reverse of this Schalke fixture last month.

But Torres is now expected to be ruled out of Wednesday's game - and could be doubtful for Saturday's home clash with West Brom and Spain's upcoming friendlies against Angola and South Africa.
