TRANSFER: Diego Costa passes medical at Chelsea

Sky sources report that Atletico Madrid striker Diego Costa has passed a medical at Chelsea ahead of his proposed £32m move to the
Premier League club.
Chelsea have met the buy-out clause in the 25-year-old's contract with Atletico and he will now negotiate personal terms.
Costa was one of the revelations of the 2013/14 season, scoring 36 goals in 52 games for Atletico as they won the La Liga title for the first time since 1996.
He had to limp out of Atletico's Champions League final defeat to city rivals Real last month after just nine minutes but is now training with the Spain squad ahead of the World Cup in Brazil.
