The 27-year-old has signed a five-year deal with the Stamford Bridge outfit, ending a three-year stay at Camp Nou, but the midfielder insists the Catalans were reluctant to sell
The 27-year-old joined the Blues in a €36 million deal last week, just three years after returning to his boyhood club from Arsenal, becoming Jose Mourinho's first major signing of the summer.
Barcelona released a statement soon after the confirmation of the move which criticised Fabregas's performances year on year at Camp Nou, but the Spain international insists the club were reluctant to sell.
"I asked Barcelona to find a way for me to leave the club. The president tried to stop the sale, but I already had my mind made up," he told Cadena Cope.
"At the time, I spoke with [sporting director] Andoni Zubizarreta and the president [Josep Maria Bartomeu] and I told them I wanted to leave.
"Honestly, it all went really smoothly. I'm not leaving for any specific reason, if not for a multitude of different things, my own errors and that’s it.
"If I didn't think that I'd be happy at Chelsea, I would've never made this decision. Above all, I want to be happy both professionally and personally.
"[Chelsea have] great players - young and talented - and building a great team with new signings. I have no doubt I'll be happy, I lived in London for eight years, I have friends [and] family there."
