West Ham boss David Moyes is wary of asking too much of Jarrod Bowen.
Moyes frustrated some fans by only giving new £20million signing Jarrod Bowen a ten-minute runout in defeat at Manchester City midweek.
Moyes said: “What we're not going to do is put pressure on him to make the difference because the boy has come in from the Championship.
“What I can tell you is he looks sharp, is match fit, and has settled quickly.
“But I have had a lot of experience with Championship players and I know the right times when to put him in — and when to not."
