West Ham are expected to approach Slaven Bilic to be their next manager after failing with their ambitious attempt to entice Rafael Benitez, Football Insider sources understand.

The Spaniard, whose Napoli contract expires next month, has rejected an offer from West Ham after holding talks with the club’s co-owner David Sullivan.

Benitez has moved to the top of Real Madrid’s shortlist to replace Carlo Ancelotti while he has also received an approach from Liverpool via intermediaries.

West Ham will turn their attention to other targets to replace Sam Allardyce, whose departure will be confirmed soon after the Premier League match at Newcastle on Sunday.

Former Hammers defender Bilic is on West Ham’s shortlist and, like Benitez, is out of contract in the summer and expected to be available.

The Croatian is currently the manager of Besiktas but 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 next season.
