As part of the 2013/14 Under-21 Premier League, a blistering end to the season saw Beaglehole's 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 Hong Kong Soccer Sevens title. 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.
