Diego Costa

He began his career with Braga in Portugal. He was signed by Atlético Madrid in 2007, who loaned him back to Braga, and then to Celta and Albacete before selling him to Valladolid in 2009. He returned to Atlético the following season and went on to become a key part of their attack, scoring 27 goals as they won the league title in 2014.

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

Having completed his medical in June,[41][42] Chelsea announced on 1 July 2014 that they "can confirm an agreement has been reached with Atletico Madrid for the transfer of Diego Costa" after they had agreed to meet the buy-out clause in Costa's contract. On 15 July Chelsea confirmed the completion of the signing of Diego Costa, who signed a five-year deal; he will earn £150,000 a week.
