Diego Costa will return to Atletico Madrid and train with the club until January, when he will be eligible to play.
Atletico are ineligible to register new players until the winter transfer market, due to their transfer ban, but Costa is eager to return to his former side after being told via text message by Chelsea manager Antonio Conte that he has no future at Stamford Bridge.
AS claim Atletico now need to make a deal with Chelsea, who are looking to sign a new striker after their Premier League title win last season.
Atletico manager Diego Simeone has also requested the club sign Sevilla winger Vitolo on a similar deal as Los Colchoneros target a La Liga title bid next season after finishing 15 points adrift of champions Real Madrid last campaign.
Atletico are unwilling to send Costa out on loan, should a transfer be agreed with Chelsea, as they believe it would be more beneficial for him to train with the first-team squad until he is eligible to play.
A plan to send Costa out on loan to a Brazilian or Chinese team had been in the works but has been discarded, perhaps due to the lower standard of football in those two countries as opposed to Spain.
Costa’s addition to the squad in January would be a huge boost to Atletico’s forward roster in addition to Antoine Griezmann, Fernando Torres and Kevin Gameiro as they target a more successful 2017-18 season.
However, a deal for Lyon striker Alexandre Lacazette may be difficult to pursue after the French club’s president confirmed Arsenal could be the 26-year-old’s next team.
