BBC Sport’s chief football news reporter Simon Stone:

Even when they are being subjected to the kind of criticism they are getting at the moment, West Ham’s ownership tend not to go in for knee-jerk reactions when it comes to dealing with managers.

Chairman David Sullivan is more likely to give someone a game or two extra rather than act when there is still a possibility the situation might be pulled round.

Clearly though, heavy home defeats by two of the club’s fiercest rivals and slipping into the bottom three is not a good look, especially when Potter’s appointment last season failed to trigger the improvement hoped for.

If there is a slight positive as far as Potter is concerned, it comes from knowing we are still incredibly early into the new season.

Julen Lopetegui collected only five points from his first six Premier League games in charge last season and it was January before he was sacked. In 2022-23, West Ham collected five points from seven games with David Moyes in charge.

The secondary point is that West Ham made four signings between 29 August and the transfer deadline closing two days later. Given there was an international break in between, how much time has Potter had to work with his new-look squad?

Next week, unbeaten Crystal Palace visit London Stadium for a game where huge demonstrations against the ownership are planned. If that game doesn’t go well, a tense atmosphere could turn toxic.

After that it’s a trip to Merseyside and a meeting with Moyes’ improving Everton before a trip to Arsenal, where West Ham have won on their past two visits, including under Potter in February.

That feels a more obvious time to reassess, even if many West Ham fans feel getting rid of the manager is only the start of the change they really want.
