Chelsea boss Roberto di Matteo may throw Marko Marin into the action tonight against Manchester United.

Marin is available for selection, with Frank Lampard ruled out due to a calf problem.

"Frank is going to be out for a few weeks. He's got a calf problem, so we will miss him and it's a big loss for us," Di Matteo said. "Apart from him everybody else is fit. Marko Marin might be in the squad for Sunday."
