Former West Ham manager David Moyes believes that
"The big thing for Marko is the change from being a winger to a striker has really reinvented him," Moyes said on talkSPORT, as quoted by Football.London.
"When we arrived at West Ham the punters weren't having him, thought he wasn't running around but the minute he's gone to centre forward he's been a revelation."
Moyes was the man who opted to use Arnautovic in at centre forward and is credited with rejuvenating the frontman whom he said he enjoyed working with.
"It was always the thing questioned about Marko, did he run or what was his attitude like? We found him great to work with," said Moyes.
"He's good enough, he could play in the top four because he's got the ability and he could play with the top players - he considers himself a top player.
"You've got to remember, he's already been at the likes of Inter Milan before, but what he needs to do is he needs to score, last season he was scoring regularly and taking his opportunities, from what I've seen this season he's not taken as many."
The striker also limped off at the weekend towards the end of the 4-0 defeat to Manchester City at the London Stadium, with manager Manuel Pellegrini simply saying the striker had a "pain" and couldn't continue.
