Besiktas coach Slaven Bilic is under serious consideration at West Ham United to succeed Sam Allardyce.

Allardyce's deal expires at the end of this season.

The Mail on Sunday says Bilic, a West Ham hero as a player, has an impressive managerial CV having coached Croatia and also has Champions League experience with current club Besiktas.

However, Bilic has not managed in the Premier League and the West Ham hierarchy are nervous about who comes in to take over from Allardyce given how crucial staying in the top-flight is next season with the club moving into the Olympic stadium in 2017.
