Chelsea have signed former Arsenal midfielder Cesc Fabregas from Barcelona on a five-year deal.
The 27-year-old had been told earlier in the summer that he was surplus to requirements in Spain, leading to speculation he was about to return to the Premier League.
Arsenal inserted a clause in the deal that took him to the Nou Camp in 2011 that gave them first option to re-sign the player.
But the Gunners decided not to take up that option and Chelsea have secured a deal for Fabregas, who is currently with the Spain squad at the World Cup.
“Firstly I would like to thank everyone at FC Barcelona where I enjoyed three wonderful years,” said Fabregas.
