Richard Dunne and James Collins headed home a 2-1 win for Villa.
Ancelotti said: “We lost the game because we had two set plays. We need to be more focused on the situation.
“We played a good game and we don’t want to lose the game in that situation, only if the other team play better than us.
“Aston Villa were very able on the set plays. We want to do better for sure. We need more concentration.”
