Cabaye started only 22 games during his 18-months spell at the Ligue 1 Champions prior to completing his £10million move to Selhurst Park earlier this summer.
Deschamps said: "He was pretty much not playing – he was lost.
"I clearly prefer that he re-finds his football, where he can show again his qualities when he is good in the head as well as his body.
"It is good news, especially for him. He is going to be happier because he is going to play."
