The Spanish-Brazilian striker has not featured for Chelsea since the FA Cup final in May, and did not join the team’s training camp in pre-season after a public dispute with both the club and the team’s manager, Antonio Conte. As a result, Costa was not included in the team’s squad for both the Premier League and the UEFA Champions League.
At times it was not clear whether Costa was going to join Atletico or not, but both clubs agreed on a fee. In fact, Atletico and Chelsea announced the deal on their respective websites.
The former Spain international will sign a contract until June 2021 and will be Atletico’s most expensive signing. Los Colchoneros will pay €55 million (£48.5m), plus €10m (£8.8m) in variables, surpassing the €40m they paid Porto for Radamel Falcao in the summer of 2011.
Atletico can officially register Costa on January 1, when the Spanish transfer window re-opens and their FIFA transfer ban ends. However, signing a new deal means that now Atletico can focus on getting Costa into the proper shape when he’s able to debut in 2018.
There is no question Costa will improve an already strong attacking line that features names such as Antoine Griezmann, Fernando Torres, Angel Correa and Kevin Gameiro, among others.
