We take a look at the contenders to be the next manager of West Ham United as the pressure increases on Nuno Espirito Santo.
The Portuguese coach was unable to keep West Ham in the Premier League last season but he stayed on at the end of the campaign as the Hammers prepared for life in the Championship.
However, West Ham have failed to win any of their opening three league fixtures this season and supporters were clearly frustrated with their manager following the 1-1 draw at Watford.
Here are our top five contenders to be the next West Ham manager in the event that the club's hierarchy opt for a change.
Scott Parker was a popular figure at West Ham over a four-year period during his playing career.
His managerial career has seen him become a promotion expert after leading Fulham, Bournemouth and Burnley to promotion from the Championship.
He is yet to fulfill his potential in the top-flight but West Ham's first priority is getting out of the second-tier.
Another popular former Hammers player, Craig Bellamy is currently in charge of the Wales national team.
He was seemingly on the brink of becoming the new Burnley manager in the summer, only for the move to fall through at the eleventh hour.
As a result, his future with Wales looks uncertain and he has proved his credentials in his early coaching career.
The former Ipswich Town manager opted to take a break from football at the end of last season.
He twice led Ipswich to promotion to the Premier League but he stepped aside in May to spend more time with his family.
The new season is only a month old and the break has not been a long one yet, but McKenna could be tempted by the chance to lead West Ham in a promotion challenge.
Former Brentford manager Thomas Frank has been out of work since leaving Tottenham Hotspur in February.
His time in North London was disappointing but his stock hasn't been damaged too much following an excellent spell at Brentford.
He may feel that he wants to go back in at the top-level and he would be quite a coup for the Hammers.
Sean Dyche has said himself that he doesn't want to be labelled as a firefighting manager.
He has walked into tough situations at the likes of Everton and Nottingham Forest in recent roles and he will want to consider his next job carefully.
A promotion challenge at West Ham could be just what Dyche needs, although his style of football might not make him popular with some Hammers fans.
