The former Olympique de Marseille boss believes the Arsenal player has no weaknesses following his match-winning performance in the qualification victory in Helsinki.
The Arsenal midfielder broke beyond Karim Benzema in the 20th minute of the match and latched on to an inch-perfect pass from the striker before steering his shot across Lukas Hradecky and into the net.
His display after returning from a lengthy spell on the sidelines impressed his coach, who said he is delighted to have him at his disposal once again.
"I do not need to be reassured by Diaby," Deschamps told reporters. "I saw him play at Arsenal. Obviously he has a lot of qualities. This is a complete midfielder, able to do everything, including scoring. Of course I prefer to have him at my disposal."Diaby himself says he is glad to be back in the fold for the Gunners and France.
"I am happy to be back. The match ended with a victory, it's a big satisfaction," he told M6. "The key is to give the best of yourself in every game."And the 26-year-old says he has put his injury woes behind him and is only looking towards the future.
"It's been a long time that I have been out of this team," he said to reporters. "I'm happy, especially because we won. The past is the past, now we must look to the future [regarding injury problems]. Am I essential [to this team]? The most important thing is to give the best of myself in every game."
