Costa publicly outlined his desire to return to Spain in an interview with Sportsmail last weekend but has now told ESPN Brasil that Atletico need to make ‘a big effort’ for his signature.
‘If Atletico and Chelsea don’t come to an agreement and Atletico don’t make a big effort, I can’t keep on wanting to play for a club that isn’t going to make a bigger effort to try and sign me,’ Costa said. ‘I know that this (big effort) will happen, but if it’s to pay the amount that Chelsea want it won’t be possible.
‘I don’t know (how much Chelsea are asking), but my agent said that Chelsea want something that Atletico can’t get near.
‘When we heard that (Antonio) Conte didn’t want me anymore, my agent went to find out if there was interest from Atletico for me coming back. But they wouldn’t pay a fortune. Atletico is a team growing every year, a big team, but they can’t pay an extraordinary amount.’
Costa hopes Chelsea will renege on their standing over the asking price and wants them to consider what he has achieved since joining from Atletico in 2014 for £35m.
He also insists on being able to choose where he plays next after being forced to accept his standing under Conte.
The Spain international says the amount Diego Simeone’s side are offering exceeds the £35m Chelsea spent on him three years ago.
‘Chelsea have offered me to several clubs, but I was very clear with them,’ Costa explained. ‘I said that if I’m not part of the manager’s plans, I would like to choose my destination. I’m not going to let them decide just to get more money.
‘When I came to Chelsea they paid a lot less compared to what’s being offered to them. I think they should take into account everything that I’ve done. ‘It’s not my fault that I’m not at the club. If it was down to me I’d be playing. ‘It’s already been one month. Holidays are good but it gets tiresome.’
