Diarra joined Arsenal on transfer deadline day for £3million but have just made one start so far this season.
Diarra said: “I have played more games for my country than for my club, which is ridiculous.
“I changed clubs in order to play and if my situation is the same as it was at Chelsea then I should have stayed where I was.
“I am not stupid. I came to Arsenal to play and I cannot stay like this for ever.
“I was only 19 when I went to Chelsea, so it was OK for me to wait for a year for my chance.
“But now I am playing for the French national team and, with the European Championships coming up, I need to play regular football.
“I cannot stay like this, going to training but staying home at weekends and sometimes playing in the Carling Cup. I cannot accept this now. I will have to decide what to do.
“If I’m not playing by Christmas, I may have to go somewhere else.”
