Foxes Under-21s Beaten By Fulham
Three first-half goals put the away side into a commanding position, before Ollie O'Neill scored twice more to complete his hat-trick and a comprehensive away triumph was completed by Luke Harris and Oliver Sanderson.
Two changes were made from the team that faced Bradford City in the Papa Johns Trophy in midweek as Sammy Braybrooke and Iestyn Hughes were replaced by Brandon Cover and Denmark centre-back Jannik Vestergaard, who was handed minutes as part of a back three.
Tawanda Maswanhise placed the first shot on target into the arms of Michael Allen, who was quick to get down, while Harris' left-footed fierce strike had to be palmed away by Chituru Odunze.
From their next attack, the Cottagers opened the scoring. Martial Godo's low cross was met by Vestergaard, who could only divert into his own net. The defender then had to be alert to block Harris' powerful drive, but Fulham doubled their advantage from the resulting corner.
O'Neill's corner was headed in at the back post by Harris after Charlie Robinson flicked the ball on. The same pair were involved again soon after, with skipper O'Neill flicking on to Harris to strike narrowly wide.
The away side continued to remain in the ascendancy, with a cross from Luciano D'Auria Henry poked past the post by O'Neill, who was on the scoresheet on 34 minutes, meeting Harris' through to convert past Odunze.
At the other end, Joe Wormleighton's deep cross was expertly controlled by Maswanhise, but Fulham's 'keeper stood tall to keep out his effort on goal. Henry Cartwright's resulting corner was headed on by Vestergaard, with Maswanhise waiting at the back post, though the forward could not beat Allen.
Two half-time substitutions saw the introductions of Terell Pennant and Hughes for Kasey McAteer and Paul Appiah and the home side did start brightly as Pennant's shot deflected into Allen's path.
But Leicester were masters of their own downfall and when Will Alves gave away possession, Fulham capitalised. Godo's cross was headed in at the back post by O'Neill on 49 minutes.
O'Neill completed his hat-trick just three minutes later, firing home from a tight angle on the left.
Chris Popov's free-kick curled over the crossbar in a rare sighting of goal for the Foxes youngsters and that would be his last involvement, replaced by Kian Pennant for the final half an hour in Seagrave.
With just over a quarter of an hour to go, O'Neill set up Sanderson to tap in a sixth from close range as the Cottagers were clinical in forward areas.
City battled on until the end, though when Kian Pennant's mazy run through the midfield set up a chance to take aim, it was wayward and off target, as was Cover's effort from a Maswanhise cross.
A seventh goal arrived with 79 minutes on the clock, Harris flicked in first-time from Henry's cross to complete the scoring.
Major moment – First-half goals
Conceding three times in the opening 45 minutes was a setback that City were unable to recover from, going further behind with four second-half goals as they pushed to try and get back into the game.
