Diego Costa will complete his move from Atletico Madrid to Chelsea on Tuesday, according to reports.
According to Sky Sports News, Costa passed a medical with Jose Mourinho's side on Wednesday and there are suggestions that the transfer - thought to be worth £32m - will be formalised next week.
Costa is believed to have asked the Atletico board to allow the move to go through ahead of the World Cup, so that he can concentrate on his exploits for Spain.
Costa was a key part in Diego Simeone's side last season, and the 25-year-old forward netted 27 goals as Atleti wrapped up their first La Liga title since 1996.
