Chelsea have confirmed the club have agreed a deal to sign striker Diego Costa from Atletico Madrid.
After reportedly undergoing a medical before the World Cup, Costa will now complete his move to Stamford Bridge after the Blues met his buyout clause at the Vicente Calderon.
A statement from the club read: "Chelsea Football Club can confirm an agreement has been reached with Atletico Madrid for the transfer of Diego Costa, with Chelsea meeting the buy-out clause for the Spanish international."
Costa becomes the second high profile arrival from La Liga following Cesc Fabregas' move from Barcelona last month.
Manager Jose Mourinho has been quietly confident of securing a move for Spain international Costa in recent weeks, recently telling the press: "Costa is a player I want in my team. I've asked the club to bring him in and I am extremely confident that we are going to get him and he'll end up signing for Chelsea."
Costa will link up with Thibaut Courtois at Stamford Bridge after the Belgian's World Cup campaign comes to a close. They could also be joined by former Atletico Madrid teammate Filipe Luis.
The left back, who was an integral member of Diego Simeone's La Liga winning side last term, has been relentlessly linked with a move to west London and his club would appear to be preparing for his departure, having signed his replacement Guilherme Siqueira from Granada.
