The English football club Chelsea have signed Spain World Cup striker Diego Costa from Atletico Madrid.
The transfer fee was not disclosed but the 25-year-old Brazilian-born player's buyout clause at Atletico was about $70 million.
Costa becomes Chelsea manager Jose Mourinho's second major capture of the close season following the signing of his World Cup team-mate Cesc Fabregas from Barcelona last month.
The club also announced that Cameroon striker Samuel Eto'o had left the 2012 European champions after spending one season in London.
Costa joins another World Cup team-mate, Fernando Torres, and Senegalese international Demba Ba as Mourinho's forward options next season.
