West Ham's Marko Arnautovic has endured a rocky start to life in London and has savagely responded to criticism from TV pundit Gary Neville. 

With the Austrian becoming West Ham's record signing this summer for £24m - expectation was high, but Arnautovic has failed to deliver. 

Sent off in his second Hammers appearance, Arnautovic has failed to secure a starting role in the side and could even be flogged off in January, as per David Moyes instructions

Following West Ham's 4-1 humiliation at home to Liverpool, Neville went in on Arnautovic saying: "He's Ronaldo in his own mind, that guy. That's his problem, he thinks he's better than he is."

To which Arnautovic has retorted, speaking to Austrian broadcaster Laola1 as quoted by Goal, "I respect what Gary Neville achieved as a player. He was brilliant at Manchester United and hats off to him.

"But what did he do as a coach at Valencia?" said Arnautovic, "His job is to criticise, that is 90 percent of his job. I am not saying Gary Neville is a nobody. He has accomplished a lot in his life, he is a legend. But as a coach? Let him stay on the TV."

The 28-year-old also lashed out at the social media critics that have been on his back ever since he arrived from Stoke. 

"Most of them have no work, probably no life and no idea" he said. "I respect the real fans and I understand them. They were all happy to have me come to West Ham because I had done very well at Stoke."

Scoring 26 times for the Potters in four seasons, Arnautovic was notoriously a player that blew hot and cold throughout the season. 

Arnautovic finished by saying: "I know how strong I am mentally, how I work on myself. I have lost nothing and I'm not in crisis. West Ham can count on me 100 per cent."
