West Ham boss David Moyes says Nikola Vlasic will start against KC Genk in tonight's Europa League clash.
Moyes admits he's had to hold back his summer signing.
He explained: "I'm looking forward to seeing Nikola Vlašić in action on Thursday.
"We really like him. We've been really pleased by him. He's come into a relatively settled side which we've got at the moment, but we'll use him tomorrow night and I'm looking forward to seeing what he can do.
"If I had my way, I'd like to let the players have the chance to settle and for everybody to get the chance to know them."
