Boss Brendan Rodgers continued to play down Leicester’s title chances despite the Foxes going top of the Premier League.
Wilfred Ndidi and James Maddison scored to beat Chelsea 2-0 at the King Power Stadium on Tuesday.
The Foxes are now a point ahead of Manchester United, having played a game more, although Manchester City will take the lead if they beat Aston Villa on Wednesday.
Just six points separate the top seven and Rodgers wants to keep a lid on any talk of a title challenge.
“Where things were rosy in December, they are not so rosy now. When you are playing well like we were you relax and settle down and this game kicks you up the backside.
“I’m able to handle the pressure. I could sense these periods would come and that’s all I can concern myself about.
“There are players who are not playing as well as they should be, that’s a simple fact.
“I’m disappointed with both the goals. We know we can compete with Leicester when we are are playing well but when you go 2-0 down and you are in a difficult period of form it affects the game hugely.
“The players know they were beaten by a better team, a team we are behind and one we want to catch. The general theme of our performance was slow and sluggish.”
