West Ham United boss Sam Allardyce admits he's seeking a big name signing.
Allardyce hopes to find a player who can make a big difference to his team.
"If we can secure that one more player, that would probably be it.
"What I want in that one player is top quality. I want that player coming in to challenge the players already here for their place immediately and keep it. That would help improve the team," he told whufc.com.
