The Hammers go to Selhurst Park on the back of victory over Fulham.
"If anybody wasnâ€™t entertained as a West Ham fan, they must be pretty miserable," said Allardyce.
"Now we canâ€™t sit back and not try and win at Crystal Palace.
"They are below us at this moment in time and Saturday will be a waste if we lose to Crystal Palace. So when we come off the pitch we have to make sure we havenâ€™t lost and if we win then weâ€™re a mid-table team.
"We will go to Palace and itâ€™s another local derby and we experienced the atmosphere there when we went in the Championship.
"I think it will be a full house and any newly promoted team gets an extra drive and support from their fans.
"Tony Pulis is very experienced and will organise his team to be difficult to beat."
