Speaking on Catalan television programme 'Gol a Gol' on Sunday, Fabregas said he was happy with life at Arsenal and could not ask for a better coach than Wenger.
"I don't know (if I'll return)," he said. "I'm fine where I am, I'm learning a lot and I'm at the ideal club to grow, with a great coach and good team-mates.
"He [Wenger] is the best coach I've ever had and the more time I spend working with him the more I learn.
"In the future I don't know, but I'm happy where I am.
"Everyone chooses their own path in life. I chose one and I can't complain. I don't know how things would have gone for me at Barca and I'd prefer not to think about it."
