Everton boss Carlo Ancelotti told BBC Sport: "We started well, got in front and had control. But second half was totally different," "Leicester changed shape, put more pressure on us and we had difficulties.
"We didn't play well but we were focused defensively.
"The team are showing a good spirit and motivation. The dream of the Europa League is very important for us and for this reason we are going to fight. There are a lot of teams fighting for the Europa League and it will be an exciting run."
Leicester boss Brendan Rodgers: "We're disappointed with the start, it's something that has crept back into the game. We gave away a soft goal, but I thought the penalty was harsh.
"I assume the responsibility for the results. That's what I'm here to do.
"We're in a strong position. We still have it within our hands to achieve what would be a dream for us. Since we've come back we've not got the performance right. The second half was better. We need to win on Saturday."
On Everton's penalty: "I think it was so harsh. We've had so many of those that we haven't had this year. It was difficult to go behind with that. It wasn't clear and obvious."
