Friday night's meeting between West Ham United and Brighton & Hove Albion went about as bad as it possibly could have for Slaven Bilic's men as they slumped to an abysmal 3-0 loss in front of their own fans.
A brace from Glenn Murray and a curling shot from Jose Izquierdo saw no response from the Hammers who put in the type of performance that makes the manager's position look untenable.
While Brighton were excellent, and Shane Duffy's performance in particular drew praise from Jamie Carragher and manager Chris Hughton, a few of the West Ham players badly let their side down.
Speaking on Sky's Friday Night Football after full-time, Jamie Carragher admitted that he had to bite his tongue in the commentary booth for fear of being accused of bullying, while Neville claimed that the Austrian forward thinks he is far better than he is.
Carragher: Awful. The type of performance that gets a manager sacked. Certain players' performances - I was very critical of Arnautovic in that game.
Huge money signing, OK you can go to a new club, it's difficult to settle, show your true form, he's been sent off, few ups and downs to start with but, his performance wasn't one of someone who was desperate to show everyone, or help the manager who has brought him in.
Walking about in the game, it was beyond belief watching him certainly in the first half and I was trying to hold my tongue actually because I felt like someone might say I was bullying him.
So poor, and just heaps so much pressure now on that manager.
Neville: You're right about Arnautovic you weren't too tough on him at all.
I think you mentioned the word application, I've only ever played with one player that had an excuse not to track back, and that player was Cristiano Ronaldo because he scored 40 goals a season.
He's Ronaldo in his own mind, that guy. That's his problem, he thinks he's better than he is.
Stern, stern but fair.
Arnautovic has yet to show anything to suggest he was worth the money paid for him in the summer, although it could be said that no West Ham player is performing at the expected level so far. Walking around the pitch won't help him anyway.
Up next for Bilic, if he is still in charge by then, is Tottenham Hotspur, and while that looks bleak it also offers the opportunity for a big performance at Wembley to be the catalyst for a return to form.
