West Ham boss David Moyes is delighted with Jarrod Bowen's new contract.
The attacker signed a new deal before the international break.
Moyes said, "People are getting lengthier contracts now and that's where it looks like football is going. I'm really pleased that we've got Jarrod signed up.
"He's a hugely important player for us and he's made a big impact across the Club over the last couple of seasons; not just as a player but as a person as well.
"I'm really pleased. He's earned it. He has started in the lower leagues, worked his way up and at every level he's had to show what he can do, and he's done that."
