The Bleus boss remains confident that the Arsenal man will shake off the exhaustion he suffered against Finland to retain his place in the starting line-up against the Belarusians
The 26-year-old spent the vast majority of last term sidelined through injury, but has already played in three consecutive matches for the Gunners this season, adding to his appearance against the Scandinavians.
"There is a risk for all players [to suffer from exhaustion]; for Diaby, perhaps a little more," the France coach commented to L'Equipe.
"He was getting tired, but I was not able to take him off as I had already made other changes. His athletic performance, particularly in the air, was fundamental to our win.
"We will see how he recovers, but in absolute circumstances, I don't see why he shouldn't be available on Tuesday."
Les Bleus host Belarus at Stade de France on Tuesday, in the second game of their World Cup 2014 qualifying campaign.
