Nigel Pearson saluted the work ethic of David Nugent after the Foxes striker hit the first hat-trick of his career in their 3-1 win over Hull.
The victory, against Pearson's former club, maintained Leicester's 100% home record and lifted them to seventh in the table.
Hull manager Steve Bruce was also ordered to the stands after an 83rd-minute confrontation with an assistant referee over a throw-in.
Nugent, who scored the 100th League goal of his career against Burnley on Wednesday night, struck the Foxes' opener in the seventh minute after Danny Drinkwater's shot had landed at his feet.
But against the run of play, Hull equalised in the 25th minute when Sone Aluko set up Jay Simpson for a simple goal.
Nugent headed Leicester in front again from a Anthony Knockaert cross just before half-time and completed his treble with a clinical finish in stoppage time.
Leicester boss Pearson said: "I think it was a deserved win. We were the better side all through the game and dominated the second half in terms of territorial advantage.
"Four home wins in a row is obviously very pleasing but clearly we need to get our away form going.
"But when you look at it in it's entirety it is 12 points from seven games in a very tough start to the season, and we could easily be three or four points better off.
"I think our performances in general have been very good. In the away games we have been a bit unfortunate or careless, and we need to try to rectify that.
"It was good for Nugent to get the hat-trick and he proved you have just got to keep working hard when things are not going your way.
"Strikers thrive on confidence and we got the result we deserved today.
"The most important thing for me is that we have got two home wins this week. When you are not picking up points away, it puts your home form under a bit of pressure.
"The two wins put us in a better position this weekend."
City boss Bruce apologised to the assistant referee after the match and admitted he had acted stupidly, but had no complaints about the defeat.
" We did not deserve anything. We have to say Leicester were worthy winners," Bruce said.
"The better team won on the day and we are very disappointed after the way we have played over the last few weeks. But we were nowhere near their level today.
"Too many of our big players did not perform to the levels they have been at. I don't think we defended well enough or did enough to put Leicester off their stride.
"We got what we deserved which was nothing.
"I have just been into see the referee to apologise. Sometimes you do some stupid things, at my age especially.
"I contested a decision that had gone against us but I still shouldn't go on like some raving lunatic, which I did and I have apologised."
