David Moyes is set to leave West Ham following Sunday's clash against Everton.

Sources claim that the Scottish manager is '90 per cent certain' to depart the London Stadium ahead of next season.

Moyes signed a deal until the end of the season, tasked with keeping the Hammers in the Premier League.

The former Manchester United boss has guided the club to survival – yet there remains serious doubt over his position ahead of next season, with the club already starting to identify possible replacements.

Former Manchester City manager Manuel Pellegrini, currently with Hebei China Fortune, is understood to be a contender, while Unai Emery, who is set to leave Paris Saint-Germain, is another who could be considered.

Moyes is expected to discuss his future with owners David Sullivan and David Gold in the coming days, with West Ham players expecting him to leave the club before the start of next season.

It took a while for the 55-year-old to convince the Hammers squad he was the man to keep them in the top flight. Slowly, though, he started to have the desired impact.

Captain Mark Noble said: 'I don't think he could've done much more, if I'm being honest. He's come in and I think the chairman would've told him we need to be a Premier League club next season, full stop.

'No matter what happens with the gaffer now, he can walk away or stay with his head held high. I'd like him to stay. I think he's good and honest.'

Moyes will be awarded a lucrative bonus of up to £2 million for keeping the club in the Premier League this season.

Moyes negotiated a cash incentive when he was appointed at the club in November, understood to be worth £1.25m to avoid relegation in 17th position, with the amount rising by £100,000 for every higher position.

The Scot could bank over £2m for a top 10 finish. West Ham could finish 10th if they beat Moyes' former club Everton at home on Sunday afternoon and other results go in their favour.

In November, Moyes was brought in as a replacement for Slaven Bilic, and he has enjoyed a relatively successful period in East London.

Survival in the top flight would also allegedly trigger talks over a new contract, with the 55-year-old currently only due to remain at West Ham until the summer.
