Frank Lampard has returned to training after the death of his mother and is expected to confirm his availability for the Champions League semi-final, second-leg against Liverpool on Wednesday.

Chelsea have not put the midfielder under any pressure to play at Stamford Bridge but it is thought he wants to take some part in the match.

Lampard missed the 2-1 victory over Manchester United on Saturday while on compassionate leave after the death of Pat Lampard from pneumonia last Thursday. He trained on his own on Sunday and was expected to join the squad today.

Manchester United were dealt a setback before the second leg of their semi-final against Barcelona tomorrow when Wayne Rooney and Nemanja Vidic missed training today.

Both were substituted with injuries at Stamford Bridge and a question mark must hang over their participation in the match at Old Trafford, even though Sir Alex Ferguson is hopeful they will be OK.

Rooney was replaced after 63 minutes having fallen awkwardly on a troublesome hip, while Vidic took a blow to his face and lost a tooth in a clash with Didier Drogba. The centre back was withdrawn after only 13 minutes.

Ferguson, the United manager, was cautiously optimistic over both players' condition when he was interviewed after the game. "Vidic has got a few stitches under his lip and he’s lost a tooth," he said.

"He was dazed rather than concussed but if we’d waited for him to come round we would have played 10 or 15 minutes with 10 men and you can’t afford that in such a big game. So we took him off.

"Wayne got the same knock as he got last week, straight on the hip bone. It takes a while for that to clear because, when you get a bang on it, it’s very painful. I’m hopeful he will be all right for Tuesday's match."
