As part of the 2013/14 Under-21 Premier League, a blistering end to the season saw the Foxes finish sixth and secure a spot in the first-ever Premier League International Cup the follow year.
That pitted them against the likes of Benfica and Schalke during a run to the semi-finals, when they were beaten in extra-time by eventual winners Manchester City.
The Foxes also achieved a top-six finish in the 2014/15 season and, with the introduction of promotion and relegation, once again maintained their elite status in 2015/16, which was a feat they would repeat the following year too - thanks to a 4-1 last day victory over Tottenham Hotspur.
In May 2016, coached by Ben Petty, the Development Squad lifted their second title at the Hong Kong Soccer Sevens - a seven-a-side summer tournament for youth teams around the world.
During the 2017/18 season, memorable victories - including a 6-1 triumph over Spurs - highlighted the progress being made as they finished third in Division 1. City's youngsters also reached the Semi-Finals of the Premier League Cup and the Hong Kong Soccer Sevens.
In the 2018/19 campaign, meanwhile, the Club's Under-23s finished 10th in Division 1, reached the quarter-finals and the Round of 16 of the Premier League International Cup and Premier League Cup respectively, while also exiting the EFL Trophy in the group stage.
Last term ultimately ended with a second-placed finish in Division 1 - settled by a points-per-game system as a result of the COVID-19 pandemic - while City also enjoyed an intrepid run in the EFL Trophy, reaching the quarter-finals after victories over the likes of Grimsby Town, Sunderland, Doncaster Rovers and Tranmere Rovers.
