Fabregas moved to Stamford Bridge from Barcelona for £30m during the summer, and has excelled during his time at Chelsea so far, making four assists in three Premier League matches.
Arsenal had a clause to buy back their former captain, but turned down the option before Chelsea pounced. Fabregas said that he had thought about leaving Barcelona towards the end of last season, and he wanted to return to London.
"I spoke with my agent and told him to find me a team," the midfielder told El Pais. "Chelsea's offer arrived and for me it was about returning to London, the place where I did best. There was no better exit. I spoke with Mourinho and he told me things that I needed to hear, I felt valued, felt that I was going to be part of something important.
"[If you'd told me five years ago that I would play for Chelsea and Mourinho] I would not have believed you, but life changes.
The 27-year-old says that while Arsenal, who played for between 2003 and 2011, will always be in his heart, he has no problems playing against them.
