Since Moyes returned to the London Stadium last December Lanzini has been largely reduced to substitute appearances, but he still managed a memorable cameo with the equaliser in the dramatic 3-3 draw at Tottenham earlier this season.

And his half-time introduction against Crystal Palace on Wednesday night helped West Ham secure a 1-1 draw, the 27-year-old playing a key role in Sebastien Haller's spectacular equaliser after Christian Benteke had given Palace a first-half lead.

"He came on and controlled the ball, gave us something different and that's what I want from the players who come on – to make a difference, be important and play their part," said Moyes.

"He's been a bit unlucky not to have been involved and start more games but the form of the team has made that difficult

"He is not someone I have given up on, I want to get him back to the levels when we were first here.

"Maybe his injuries affected him a little bit, but then we need to find a way to get him back there."

Benteke's evening ended prematurely after he was sent off for a second yellow card following two identical aerial challenges, a decision manager Roy Hodgson branded "ludicrous".

Eagles defender Scott Dann told Premier League Productions: "It looked like an honest challenge.

"It seemed to me as if Christian jumped up on both of them. When you're a centre-back and a big striker going for the ball you know you have to jump with your arms.

"I think if he made a movement towards them, fair enough. But he's jumping up straight, the guy's jumping up from behind.

"He's obviously disappointed. He doesn't feel as if he should have been sent off."
