David Moyes has admitted that uncertainty around his future could cause issues within West Ham.
The Hammers manager's contract is up at the end of the season and there have been few advancements made over a potential new deal, despite the Scot delivering European silverware for the club last season.
It is believed that a decision won't be made on his future until the end of the season with the Hammers fighting in the Europa League and again for a European place in the Premier League.
It is Moyes's second spell in charge of the club, and the fan base appear split on his position, despite the success in last season's Europa Conference League.
