West Ham United boss Sam Allardyce hopes for more from Nene against Chelsea tonight.

Nene made his debut in defeat to Crystal Palace.

"He has the ability to change a game, it was just a shame that his shot didn't go in. That was a key moment in the game and might've changed the result, as was Mark Noble's shot that hit the crossbar," Allardyce told whufc.com.

"There were times in the game that could've changed the course of the game and get back into the game. The overriding disappointment was spending so much time on Palace's set pieces but it didn't pay off. We now face Chelsea, our third local derby in a row, who are the best team in the league."
