Rabiot said that coach Laurent Blanc told him that he would prefer that he stayed at the club to earn his place than go out on loan again.
"In terms of playing time, a first step has been taken. I play more regularly. I am no longer the little kid who starts," Le Parisien quotes Rabiot as saying.
"My loan at Toulouse did me a lot of good. I played 13 Ligue 1 matches. This experience gave me personal landmarks and I showed others what I can do, including my teammates at PSG.
"In early August, Laurent Blanc took me aside to tell me that he was counting on me and that he was opposed to the idea of me leaving on loan."
Rabiot, 18, has played 12 times in the league for PSG so far.
