Nigel Pearson's side have slipped to third in the Championship following a run of three league games without a win, and entertain a team who have scored an incredible 47 goals in 16 Premier League outings this term.
The firepower at Manuel Pellegrini's disposal is perhaps best illustrated by the fact City have scored nine goals in their last two matches, against Premier League leaders Arsenal on Saturday and UEFA Champions League holders Bayern Munich last week.
Such is the strength of the Chilean's squad, 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, who have 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.
