Marko Arnautovic needs to do more, insists West Ham boss Slaven Bilic: 'I want him to push the borders'

West Ham's record signing Marko Arnautovic has plenty of ability but needs to venture outside of his comfort zone more often, according to manager Slaven Bilic.

The Austrian playmaker set up goals for Angelo Ogbonna and Diafra Sakho before Arthur Masuaku sealed West Ham's 3-0 Carabao Cup win over Bolton Wanderers at the London Stadium on Tuesday.

Despite his contribution, Bilic demanded more from Arnautovic, who West Ham prised from Stoke City for a reported fee of £25million in the off season.

'I could have asked for more. I want him to do more. He's got that quality and that something extra,' Bilic said after the game.

'I like him as a player but sometimes he gets happy with the few things that he does when I want him to push the borders.'

Arnautovic was sent off in the 3-2 Premier League defeat to Southampton last month and Bilic said Tuesday's display marked the beginning of a comeback for the Austrian international.

'I know what he's capable of and I want him to keep molesting the opposition and never be happy in a positive way. But of course he did the job here,' Bilic said.

West Ham, who drew 0-0 with West Bromwich Albion last week after posting their first Premier League win of the season against Huddersfield, host Tottenham Hotspur on Saturday.
