West Ham United boss David Moyes hopes Marko Arnautovic can produce another match-winning display against Stoke City on Monday.
The 28-year-old Austrian moved from the Potters to West Ham last summer and has shown flashes of his potential at times this season.
He struggled during the first few months of the campaign but improved once Moyes had replaced Slaven Bilic as Hammers boss, with one of his best displays coming in the 3-0 win at the us Stadium in December.
Arnautovic has scored nine goal in his last 14 appearances and was at his imperious best again recently when West Ham beat Southampton, who are now managed by his former Stoke boss Mark Hughes.
"Players like Marko need a little bit of leg room, maybe more than others, and I think we gave Marko his leg room but I want to make sure he knows he has got to do the job here," Moyes said.
"I don't think he will (slack off) now, because he knows what got the crowd from booing him to cheering him every week and becoming one of their heroes."
West Ham can be backed at 1/1 to beat Stoke City while Arnautovic is 13/10 to score at any time against his former team, who are 1/8 to be relegated this term.
