Rémi Garde admits the claret and blue playing camp are buzzing after the Crystal Palace win - but he won't allow them to get carried away.
Garde said the dressing room was jumping after Villa's first Barclays Premier League win since the opening day at Bournemouth.
The boss was delighted with the confidence boost the three points have offered.
But he wants the players to get their heads down again now as they prepare diligently for the visit of Leicester on Saturday.
Garde believes one of the reasons for success on Tuesday was the studious way the team followed his instructions.
And he knows concentration will be key this weekend.
He said: "The players were very happy in the dressing room as you can imagine.
"But they can't afford to be too happy for too long because we have another very important game coming up here against Leicester.
"It was important to win but every game is different - and the Leicester match will be a different challenge for us.
"I was, of course, very pleased to be fair with the way we played football against Palace - I thought it was very entertaining. I thought we had an attacking spirit - and I liked that.
"The 11 players also worked very hard for the team. Everyone was focused on the strategy I put forward for the game. They were very concentrated on that.
"Now we hope we are building something. But it will be very tough against Leicester because they have quality players.
"It's about recovering and preparing very well for the next game."
