West Ham United have a 'big worry' about replacing David Moyes as manager, according to journalist Dean Jones.

The Lowdown: Moyes' future in doubt?

Amidst a difficult season for the Hammers in the Premier League, there have long been question marks about Moyes' future as manager, although he has so far managed to do just enough to keep his job.

The Scot is still said to have an 'excellent relationship' with the club's hierarchy, which could be a key reason why he is still in charge, as performances on the pitch have not been up to scratch, with his side currently in the relegation zone.

Given that there is just under a third of the season to go, it may well be a risk for West Ham to part ways with their manager at this stage, and he has also overseen a good run in Europe, with the Hammers safely through to the quarter-final of the Europa Conference League.

The Latest: Jones' update

In an interview with GiveMeSport, Jones suggested the reason David Sullivan and co are yet to sack the 59-year-old is due to a lack of available replacements that would be a real upgrade. The journalist said:

"There are loads of managers out there, but who's going to actually want this job? I think that's what West Ham are trying to gauge in the background while this season plays out.

"Can they actually find a manager that is a guarantee to be an improvement on Moyes? That's their big worry. Their big worry is that Moyes is actually the best manager they can get."

The Verdict: Should Moyes go?

It is evident that West Ham have been weighing up potential options to replace the former Everton boss, with it recently being reported they 'delivered a remarkable contract offer' to Jose Mourinho, although it did not appear to interest him.

As such, the Hammers' best course of action now could be to wait until the end of the season before approaching anyone else, as they are unlikely to attract the best applicants at present, given their current league position.

However, managing West Ham may be a very attractive proposition at the end of the season if they retain their Premier League status, as they could also have Europa League football to offer, should they go on and win the Conference League.

It may seem harsh to part with Moyes if he manages to win the club's first major honour since their FA Cup triumph in 1979-80, however, league performances have been very concerning this season, and a new manager with fresh ideas could do the Hammers the world of good.
