AC MILAN are back in the hunt to sign Diego Costa because they know he will eventually agree to leave Chelsea this summer, according to reports.

Costa has already snubbed interest from Milan in a bid to force a move to Atletico Madrid.

Atletico cannot field any new signings until January because of a FIFA-imposed transfer ban.

It leaves Costa’s future in limbo, with Chelsea keen to sell for £50million but the player unwilling to leave for anywhere but Madrid.

But Italian newspaper Corriere dello Sport claim Milan are hoping to convince the Brazil native to change his mind over their interest.

According to the report, next summer’s World Cup in Russia means Spain international Costa is guaranteed to leave Chelsea before deadline day next Thursday.
