Returning Chelsea boss Jose Mourinho is hoping Frank Lampard plays for England against Scotland on Wednesday to build up his match fitness.

While many managers will send their players away for the midweek international friendlies fearing injuries, Mourinho believes the game will prove positive for his veteran midfielder.
Lampard, 35, has played just once in pre-season -- 45 minutes against Real Madrid in Miami during Chelsea's tour of the United States -- and while he might feature against Roma on Sunday the midfielder is still playing catch-up.
Mourinho said: "Frank's not ready yet, he still has to train. He has to play against Roma on Sunday. He played 45 minutes against Real, maybe he plays 60 minutes against Roma.
"He's in the England squad, so it will be good if he plays against Scotland."
David Luiz and Juan Mata are not yet fully fit and Mourinho is being cautious about rushing them back into action and causing further problems.
He added: "They are important. The team with Luiz and Mata is a better team. But again we don't risk players in pre-season. Mata had a little injury so we didn't take a risk. David had a hamstring injury so we said 'stop'.
"I'm not risking him here so, hopefully, there's no problem for the start of the season."
