Nigel Pearson's side has slipped to third in the Championship following a run of three league games without a win, and now entertains a team that has scored an incredible 47 goals in 16 Premier League outings this season.
The firepower at Manuel Pellegrini's disposal is perhaps best illustrated by the fact City has scored nine goals in its last two matches, against Premier League leader Arsenal on Saturday and Champions League holder Bayern Munich last week.
City has also scored seven across two Capital One Cup matches this season, following up a 5-0 hammering of Wigan Athletic with a 2-0 win at Newcastle to book its quarterfinal spot at the King Power Stadium.
Pellegrini has used the Capital One Cup as an opportunity to rest some of his star players, with the likes of Sergio Aguero — who is sidelined for this contest by a calf injury anyway — and Samir Nasri yet to feature in the tournament.
Such is the strength of the Chilean's squad, as that policy simply means other international stars such as Edin Dzeko — a scorer against both Wigan and Newcastle — and Stevan Jovetic have been given a chance to shine.
Leicester, which has overcome Wycombe Wanderers, Carlisle United, Derby County and Fulham to reach the last eight, can take some heart from City's away form.
Pellegrini's men have managed 11 wins and 50 goals from 12 games at the Etihad Stadium this season, their sole defeat coming at the hands of Bayern.
Yet they have been beaten in four out of 12 away fixtures in all competitions — losing to Cardiff City, Aston Villa, Chelsea and Sunderland — while also being held to draws by Stoke City and Southampton.
The last time the clubs met at the King Power was in January 2011, when Leicester held City to a 2-2 draw in an FA Cup third-round meeting before the Premier League giants ran out 4-2 victors in the replay.
