AKIPRESS.COM - Striker of Spain Diego Costa has formally completed his move to English Premier League team Chelsea from Atletico Madrid, Irish Sun reported.

“Chelsea Football Club is delighted to announce Diego Costa has today completed his transfer from Atletico Madrid by signing a five-year contract,” the London club said in a statement Tuesday.

Chelsea met the buy-out clause for the Brazil-born forward and paid a reported transfer fee of around $55 million.

Costa, 25, scored 35 goals for Atletico last season as they won the Spanish title and reached the Champions League final, only to lose in extra-time to city rivals Real Madrid after they had defeated Chelsea in the semifinal.

He began his career with Braga in Portugal. Internationally, Diego Costa played twice for Brazil in 2013, but later declared his desire to represent Spain, having been granted Spanish citizenship in September 2013. He made his debut for his adopted nation in March 2014, and was selected for that year's World Cup.
