West Ham boss David Moyes says teenager Ollie Scarles could see action tonight at Anderlecht.
Moyes says the youngster is in his squad for the Europa Conference League tie.
He said, "We've brought Ollie Scarles with us here, who is 16.
"He will be involved and I do know that Anderlecht have a couple of 16 to 18-year-old players too. So it's a great thing that young players get opportunities and some of them will play.
"We used a lot last year and we have a new group with the U23s now, and we're trying to promote the younger ones even sooner if we think they're doing well. And Ollie is doing really well."
