"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 told West Ham's website http://www.whufc.com.
"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, who have yet to win consecutive home league games this season, can climb to 12th in the table, nine points clear of the relegation zone, if they beat Stoke.
