The young Spaniard has admitted he is having doubts about signing an eight-year deal with the Gunners, with concerns about the futures of both Wenger and Thierry Henry.
"It could be that I have doubts," said Fabregas. "Before I was very sure and I signed for eight years.
"I was sure that this was the ideal club for me but now maybe I am not so sure when I see that the coach has not renewed his contract, that the president has gone and I don't know what Thierry Henry is going to do.
"These are all things that could have an influence on my future.
Fabregas told Spanish newspaper El Mundo Deportivo: "If Wenger goes I'm 90% sure I will leave. I identify the team with him, and without Wenger, Arsenal wouldn't be the same."
