Chelsea boss Roberto di Matteo admits David Luiz is struggling to make the Champions League semi against Barcelona.

Luiz was carried off on a stretcher in a challenge that lead up to Gareth Bale's goal in their FA Cup semifinal win over Tottenham yesterday.

Di Matteo said: "He picked up a hamstring injury so we'll have to assess him tomorrow, but it looks to be doubtful at the moment for the next game.''
