Chelsea ace Didier Drogba is struggling to make their Champions League second-leg clash at Barcelona.

The Daily Mail says Drogba will miss Saturday's crucial Barclays Premier League showdown with Arsenal because of a knee injury and is a major doubt for Tuesday's Champions League semi-final second leg against Barcelona.

The striker picked up a knock to his left knee during his match-winning outing against Barca on Wednesday and his injury will be assessed today by the club to see if he can play in the return game at the Nou Camp.
