Manager Nigel Pearson hailed Leicester's sixth successive home win that kept them top of the npower Championship table as "a good night's work".
The Foxes beat Brighton 1-0 to maintain their 100 per cent record at the King Power Stadium and extend their unbeaten run to seven matches from which they have picked up 19 points.
Pearson said: "After the draw at Birmingham it was important to get maximum points from this match and the Crystal Palace game coming up on Saturday. They are both tough matches and this league is pretty relentless. So all credit to the players. They have worked hard in games and on the training ground, to get us to where we are at the moment."
He continued: "I don't think we had the energy levels we have shown for the majority of the season but we managed the game better, especially when they went more direct towards the end of the match."
Disappointed Brighton boss Gus Poyet once again blamed a lack of goals for the defeat.
He said: "I have been saying the same thing for the last four or five weeks. No matter how you play, how well you pass the ball and keep the ball it is all about scoring goals. I am getting bored listening to myself because it is always the same.
"I don't try to put myself in a better position than we are.
"The table shows we lost 1-0 and it was the same last week and the week before. But the best chance of the game was for us. We seemed to be happy controlling the game but to score goals you need to attack.
"Players these days want to be told everything and we are making them machines.
"Getting the ball in the net is the most difficult part of the game. It is our own fault. We cannot blame anyone else."
