Diego Costa joins Chelsea: Blues announce the signing of former Atletico Madrid striker on a five-year deal
Spanish striker signs a five-year deal at Stamford Bridge
Chelsea have announced the signing of Atletico Madrid of Diego Costa on a five-year deal.
The fee is undisclosed but in the region of £32m.
The 25-year-old becomes the third signing of the summer, following Cesc Fabregas from Barcelona and Mario Pasalic from Hajduk Split.
"I am very happy to sign for Chelsea. Everybody knows it is a big club in a very competitive league, and I am very excited to get started in England with a fantastic coach and team-mates," he said on the club's website.
"Having played against Chelsea last season I know the high quality of the squad I am joining.
"I would like to thank everybody at Atletico who made me into the player I am, it was an incredible time for me, but now I am starting a new adventure and I hope to win many trophies with Chelsea."
A club statement on chelseafc.com read: "Chelsea Football Club is delighted to announce Diego Costa has today completed his transfer from Atletico Madrid by signing a five-year contract.
"He will join up with the first team for our pre-season European training camp next week."
Despite struggling in Brazil as Spain crashed out of the World Cup, Costa enjoyed a prolific season for Atletico last year.
He scored 36 goals in total, with 27 of those coming in La Liga, as Atletico lifted the Spanish title for the first time in 18 years and reached the final of the Champions League.
Jose Mourinho is still expected to make additions to his squad, with left back a priority. Costa's former team-mate Filipe Luis is his top target, but the two clubs are struggling to find a fee they can agree on.
It also remains to be seen whether Petr Cech or Thibaut Courtois will be No 1 for the Blues next season.
Chelsea are this summer electing to forego a major pre-season trip outside of the EU in favour of staying closer to home.
They will play lower league opposition in Wycombe Wanderers and AFC Wimbledon before heading on a European trip to Hungary, Slovenia, Austria, Germany and the Netherlands. They then play Real Sociedad at Stamford Bridge just four days before travelling to Burnley for their Premier League opener.
