Chelsea have signed former Arsenal midfielder Cesc Fabregas from Barcelona on a five-year deal.
The Spaniard, 27, spent three years at Barca and joins the Blues after Arsenal turned down a first option to buy him.
Fabregas, on World Cup duty with Spain, said Chelsea matched his football ambitions, adding he had “unfinished business” in the Premier League.
“I considered all the other offers very carefully and I firmly believe that Chelsea is the best choice,” he said.
“They have an amazing squad of players and an incredible manager. I am fully committed to this team and I can’t wait to start playing.”
