David Moyes will have learned an awful lot about West Ham after their defeat at Watford in his first game in charge, and not much of it was good.
The new Hammers boss already knows his players are not fit enough but what he also found out on Sunday is how some of them are short of confidence and character too.
Off the field, there are more problems. The supporters are completely disenchanted, as was made clear from their banners and chants at Vicarage Road, although their anger was not directed at him.
The defeat meant West Ham stay in the bottom three and the only positive for Moyes was that, despite a poor performance, his side still managed to create some very good chances, and should have scored at least two goals.
But that should not mask the fact Watford fully deserved their win. The Hornets completely dominated the game and, at times, things were far, far too easy for them.
Moyes’ first home game, against Leicester on Friday night, is going to be another big moment for him.
From what I saw and heard at Vicarage Road, the atmosphere at London Stadium is not going to be a positive one.
The West Ham supporters are clearly angry and disillusioned with the club’s owners, and some of the players too.
