Chelsea striker Radamel Falcao has returned to training and could face his former side Porto on Wednesday.

The Colombian international has been out with a muscular problem which has plagued the start of his time at Stamford Bridge.

Falcao has made just 11 appearances for the Blues so far following his loan arrival from Monaco in the summer, but with Diego Costa suffering a poor run of form in front of goal, under-pressure Jose Mourinho could look to the 29-year-old for their European clash on Wednesday.

Chelsea face the striker’s former side at Stamford Bridge knowing that a defeat could see them eliminated from the competition.
