On the back of successive draws with Chelsea and Crystal Palace, the young Foxes returned to Seagrave at the weekend by hosting U18 Premier League South title chasers Arsenal.
It would ultimately be a frustrating day for the side coached by Adam Barradell, as Michal Rosiak netted just six minutes in.
Osman Kamara's 54th-minute penalty was followed by another effort from the Gunners youngster eight minutes later. An unfortunate Ryan Donnelly own goal, on the other hand, completed the scoring, leaving City eighth in the table.
A Premier League Cup Quarter-Final is next up for Leicester, away at Chelsea, on Saturday (12pm GMT kick-off).
