Diego Simeone insists he will not stand in Diego Costa's way if he has a chance of joining Chelsea this summer.
Sky Sports reports how the Atletico Madrid manager has given the clearest indication yet that the prolific striker could complete a big-money move to the Premier League when the transfer window reopens.
"It will depend on him and what he thinks is best for his future," the Argentine coach told Spanish radio station Onda Cero. "I will support any decision he makes.
"It's natural that Chelsea are interested in him and that makes me happy, because my aim and that of my coaching staff is to see our players improve."
Jose Mourinho has been credited with an interest in bringing the Brazilian-born Spain international to Stamford Bridge, as he looks to strengthen Chelsea's forward line ahead of the 2014/15 campaign.
Costa has been the standout player in Atletico's exceptional season to date, with his 26 goals in 31 Primera Division matches giving his side an excellent chance of winning the club's first La Liga title since 1995/96.
Simeone's side are also still in contention for the Champions League, and have been drawn against Chelsea in the semi-finals of Europe's elite club competition.
If selected, Costa could turn out against his potential future employers, as the west London club consider a bid for the 25-year-old this summer.
"We understand that Chelsea have huge financial power and if he wants to live off football for the rest of his life, I will have no problem in him going," Simeone added.
"It was like Radamel Falcao - how could I tell him not to go to Monaco? He gave life to this club."
