Fabregas has struggled to secure a regular place in the Barca team since joining from Arsenal for £30million in August 2011.
That led to Manchester United coming in for him this summer but David Moyes was twice rebuffed after making bids for the 26-year-old, with the Spanish champions insisting they had no plans to sell him.
Fabregas himself is happy to stay with the Catalan club and remains focused on enjoying success at Barcelona.
"The tougher the challenge the better I like it and Barcelona was the biggest and most difficult, and I want to finish in a happy manner and if I can retire at Barca, then so much the better," he said.
"The only thing in my head is triumphing at Barcelona.
"When I arrived at Barcelona I already knew there were other places where I could earn more or where I could have more minutes, but coming to Barca was my dream.
"It was my dream since I was small. I wouldn't go, not even for double the money."
