Chelsea manager Jose Mourinho has indicated Frank Lampard could miss the start of the season due to fitness concerns.
The veteran midfielder, who has received an England call-up for Wednesday's friendly against Scotland, has been nursing niggling knocks throughout pre-season.
And although he came through 45 minutes against Real Madrid in Miami, and is likely to get an extended run-out in a clash with Roma on Sunday, Mourinho feels the 35-year-old still has some way to go.
"Frank's not ready yet, he still has to train," Mourinho said.
"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."
Meanwhile, Mourinho is also erring on the side of caution with influential duo David Luiz and Juan Mata ahead of the 2013/14 campaign.
The Portuguese 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."
