West Ham capitulated on Saturday afternoon at home to Watford despite looking comfortable at 2-0 up.

The Hornets fought back and demolished the Hammers 4-2. To make matters worse, there were toxic scenes in the crowd with West Ham fans fighting amongst each other.

Big things were expected of West Ham this season with their new stadium and record transfer signings. It hasn't all gone to plan so far though as they only have three points from their four Premier League matches and were knocked out of the Europa League qualifying stages by Romanian side Astra Giurgiu for the second season running.

The problems in the stands only serve to enhance the mood that things are not rosy on or off the pitch for the Irons at the moment.

However, focusing on pitch matters only, we have analysed who was particularly at fault for West Ham's extraordinary demise this weekend...

The West Ham shot-stopper replaced the incumbent Jussi Jaaskelainen as the first team goalkeeper in 2013/14 and has been their No.1 ever since.

He even won save of the season once for his fingertip stop versus Oscar of Chelsea.

However, Adrian didn't have one of his finer games this weekend.

The first goal was a deflection so blaming him would be harsh but the second goal showed a huge lapse in communication with his defenders which proved costly.

It was the third goal, though, that the goalkeeper will be particularly disappointed with as Ettienne Capoue's shot was very much savable but instead the No.13 didn't get a strong enough hand to it and watched the net ripple to hand Watford a surprising lead.

Eventually, West Ham succumbed to Watford again, conceding a fourth goal. We're big fans of Adrian but there's no denying he let the Hammers down on Saturday.

James Collins

James Tomkins

Collins is in his second spell as a West Ham player having rejoined them in 2012. He is one of the leaders at the back and has been a consistent performer over the years.

However, like Adrian, Collins had an absolute shocker this weekend.

He was a huge part of the calamitous second goal as he headed the ball back towards the keeper despite Adrian already rushing out of his goal to deal with the loose ball himself. The miscommunication was costly as Watford equalised before the break and took that momentum with them into the second half.

Collins was not just susceptible for their second goal but he looked uncomfortable throughout the match and was arguably one of the Hammers' worst performers on the day.

He was certainly up there with one of those that let them down massively.

Sam Byram

Sam Byram

The young full-back has a huge future in the game. He has been likened to Gareth Bale, who also started out as a full-back before maturing into a wonderfully power winger adept at both defending and attacking.

However, this was not a game Byram will enjoy looking back at any time soon.

He was easily tricked by Odion Ighalo for the Hornets' first goal, which gave Watford the impetus they needed before dismantling the Hammers.

Unfortunately, Byram didn't quite look at the races all day as he was given a torrid time down Watford's left flank.

It felt as if every time they attacked, they would create something meaningful.

Byram is only young, though, and there's plenty of time to improve but when it comes to pointing the fingers for Saturday's horrible defeat, it's hard not to point Byram's way.
