The Toffees blew a chance to overtake Chelsea on the standings, putting their top-four hopes in jeopardy.
"They played better than us," Ancelotti said. "They deserved to win. We were good defensively for 30 minutes. When they scored, the game became difficult for us. They are a good team.
"Jordan did well. For the penalty he can do better but it doesn't change the performance. I think it was a penalty.
"The game that we planned was what we got for 30 minutes. But we have to be honest, we are not at the same level. We cannot play an open game against this kind of team. It was the plan to play the same way as we played against Liverpool, but against Liverpool we scored early.
"We are looking to fight for Europe. This is good for us. We will be there until the last game. We are disappointed for this defeat but no tragedy. We look to the next game."
