Chelsea star Diego Costa has been linked with a return to Atletico Madrid in the summer, after the Spaniard has often found himself surrounded by controversies.

It had been earlier reported Costa is also keen on a return, but it won’t be easy for Atletico Madrid to prize him away from the Blues.

According to the latest report in Spanish newspaper AS, Chelsea are not prepared to let Diego Costa go until they sign at least two strikers.

AS reckon Antonio Conte is set to play his trademark 3-5-2 formation at Chelsea, and the Blues will have to sign at least two forwards, before considering selling Costa.

It is reported Chelsea want Alvaro Morata, Gonzalo Higuain, and Romelu Lukaku this summer, and each of them are expected to cost at least €60m.

Chelsea would expect Atletico Madrid to pay a similar figure for Costa, and they’d also have to match his yearly wages of €12m.

Diego Simeone is very keen on bringing Costa, after losing two Champions League finals, and Atletico Madrid could very well try to convince Chelsea and the player, but any transfer looks very difficult at the moment.

Costa was also initially keen on a return, but AS say he has his doubts now after Conte promised him a key role in the team.
