Aly Cissokho says Villa must play to their top level to make it through to the FA Cup fourth round.
Cissokho knows that the team were below-par in the first third round game at Wycombe, with a 1-1 draw leading to a replay this evening at Villa Park.
The left-back has been pleased with the quality and intensity of performances against Palace and Leicester in the last two Barclays Premier League matches.
And he believes the same again will be required to defeat the Chairboys.
He said: "The players are looking forward to this FA Cup game - it's good for us to play in this competition.
"We are going to play very seriously. We have to be ready.
"The game we played there was not good enough for going through.
"We have to make sure we win tonight now.
"We have to play every game with the same spirit as the last two games.
"We showed we have character. We fight until the end. If we don't do that tonight, it will be hard.
"We have to remember the game there. When you don't play to your capabilities they can be on the same level.
"We have to prepare well and make sure we win this game."
