France coach Laurent Blanc revealed that Yann M'Vila has returned to fitness following his ankle injury, but said he was unlikely to start Monday's opener against England.
"For Yann M'Vila, Blaise Matuidi and Steve Mandanda, the news is pretty reassuring," said Blanc.
"That's to say that they will train with the group tonight (Sunday). The medical staff have done remarkably well to get them back as quickly as possible."
He added: "The three players are ready to train but there's also a risk. But if you worry about risks too much, you'll finish the Euro without having used any of those players.
"Our objective is to pick the best team possible. I think it'll be hard for those three to start, but they should be in the squad."
