West Ham are closing in on the appointment of Slaven Bilic as their next manager, Football Insider sources understand.

The Hammers turned to the Besiktas manager after failing in an ambitious attempt to entice Rafael Benitez, who is set to be appointed the new Real Madrid manager later this week.

Football Insider revealed last Wednesday that Bilic was the new frontrunner for a post that became vacant when it was announced that Sam Allardyce’s contract would not be renewed.

Former Hammers defender Bilic has held talks with West Ham’s co-owner David Sullivan and is set to be offered the chance to succeed Allardyce.

The Croatian is currently the manager of Besiktas but his contract will shortly expire and he has said that he does not expect to be in charge of the Turkish club next season.

West Ham co-owners Sullivan and David Gold have been working on a list of potential managers to take the club into the Olympic Stadium the season after next.

Benitez had been set to accept the post before he was offered the Real Madrid job while David Moyes has also been sounded out but he is not willing to leave Real Sociedad.
