Paul Hart has called for Crystal Palace supporters to pack out Selhurst Park for Monday night's crucial match with West Brom.
The Eagles are desperate for points to move clear of the Championship drop zone and avoid a nail-biting relegation decider against Sheffield Wednesday on the final day of the season.
In their last home game, against Queens Park Rangers, Palace recorded their second biggest league attendance of the season but the players failed to live up to expectations, losing 2-0.
Hart hopes a similar attendance will inspire his squad to make amends.
"Our supporters have not let us down at any point and I think we will get a big crowd and a big atmosphere," he said.
"One thing I do know is if we get a big crowd we have to deliver for them.
"Last week we had a fantastic crowd and did not do ourselves justice so I am hopeful we will get ourselves up for it."
