​Besiktas are lining up a shock move for unsettled Chelsea striker Diego Costa, the Express  reports, despite recent talk suggesting that Atletico Madrid were on the verge of securing their former star.

Having infamously been told by Antonio Conte, via text message, that he is no longer wanted at Stamford Bridge, the Spaniard has seemed keen to force through a return to Atletico Madrid, rejecting a lucrative move to the Chinese Super League, as well as advances from the likes of AC Milan and Juventus.

However, his former club's transfer ban is holding up the process; a move cannot be completed before the New Year. While Costa is prepared to wait for this, Conte is keen to offload the £150k-a-week man before the new season begins. 

This standoff is hindering Chelsea's pursuit of potential replacements, with Everton's Romelu Lukaku seemingly top of the list.

Besiktas have now emerged as more immediate option than a return to the Spanish capital for Costa. The club's chief, Fikret Orman, is keen to build a side capable of dominating the Super Lig in Turkey, as well as making greater headway in Europe. 

To this end, the signature of Pepe, who had seemed destined to join PSG following his release from Real Madrid, has already been secured, indicating that Orman means business.

The Turkish champions have already made an attempt for Costa's signature during his days at Atletico, and, while they were unsuccessful six years ago, Conte's desire to get rid of the Spanish striker means that they have a good chance of landing him this summer.
