Leicester boss Brendan Rodgers: "You have seen the real spirit of the side tonight. We were a real threat going forward.
"The performance and maturity of the team was pleasing. I knew we were playing against a talented team and we had to be right on our game."
Leicester midfielder James Maddison, speaking to BBC Sport: "I feel good, I feel sharp. I feel good in front of goal which is always a good sign as an attacking player.
"Everyone talks about the title, every week it is said a different team will win it. We will just go about our business and let you talk about that.
"The gaffer has been here two years, he has really stamped his authority on the group. We are playing well consistently. We have learned our lesson from last year by showing more consistency.
"Tactically we controlled Chelsea without the ball at times as well and it."
Chelsea boss Frank Lampard, speaking to BBC Sport: "Very disappointing [to concede early]. Sometimes when you are in the from you are in it can happen - it's not an excuse. More disappointed by the second goal. Leicester are a good team in form, we are not in good form. We could do better, I'll not dress it up any other way.
"We were in a really good place in December, second in the league and two points from the top. Maybe complacency set it. There's only one way out of it which is hard work. Today Leicester were in better form than us.
"It is clearly concerning. It is a period we are not happy with, other clubs have been in that period. All we can think about is getting through the period, working hard. The important thing is the players bounce back. This is the cut-throat nature of what it is.
"The players have to keep their heads up but also keep their eyes open and review the game and see there was an energy in the Leicester team we didn't have.
"You cannot be sluggish and slow because it won't work against a team like Leicester that are firing.
"Might be a big ask to answer realistic expectations. Last year was probably top six or top eight. The changes that have happened means we have maybe lost momentum, we are striving to find the pressing speed we had last year. The expectations have to be what are we going to do next week, next game, next training session."
