Jack Collison has hailed the support of West Ham United's fans this season.
The Wales midfielder says the players have never felt under siege from the Upton Park support.
Collison told whufc.com: "Their support is what we need. It is a huge game. It is very tight down the bottom and it will be great if they can be our 12th man.
"The fans haven't got on our back at all this season - even at times when we haven't played too well, they have been superb Hopefully we can pay them back."
