Leicester surged back to the top of the Championship with a record-equalling 3-0 win against promotion rivals Preston on Wednesday.
The Foxes had been knocked out of pole position by Ipswich's victory against Hull on Tuesday but they responded in emphatic fashion at the King Power Stadium.
Two second-half goals from Kiernan Dewsbury-Hall either side of a Kelechi Iheanacho strike sent a message to the rest of the second-tier promotion chasers.
The victory was Leicester's ninth in their 10 Championship matches this season, moving them two points clear of Ipswich as they chase an immediate return to the Premier League after last season's relegation.
Leicester have equalled the best start to a Championship season, matching Sheffield United's 27-point haul from the first 10 games of the 2005-06 campaign.
"I just said to the players that what you have done today is something that is not normal," Leicester boss Enzo Maresca said.
"And not only because your club is Leicester have you achieved something like this. There are other clubs in the Championship who are important like us but they struggle.
"So it is something important, but it is early days."
