Reserves In the early 1950s,
reserve teams were incorporated into the
third tier of the senior
Scottish Football League, with Aberdeen 'A' taking part for six seasons of the arrangement. Aberdeen fielded a team for many years in various separate reserve competitions culminating in the
Scottish Premier Reserve League, which was abandoned in 2009. In July 2018, it was reported that reserve leagues would be reintroduced in lieu of the development leagues that had been in place since 2009 (below). The top tier of the new
SPFL Reserve League featured 18 clubs, whilst a second-tier reserve League comprised nine clubs. Other than a minimum age of 16, no age restrictions applied to the leagues. Aberdeen intimated at the end of its first season (2018–19) that they would withdraw from the Reserve League to play a variety of challenge matches, several others did likewise. They later entered a small league (under-21 plus three overage) along with three other Scottish clubs and
Brentford and
Huddersfield Town from the English leagues.
Youths Prior to the introduction of the
Scottish Premier League in 1998, the Under-20s previously competed in the youth league administered by the Scottish Football League. An under-20 side then took part in the
SPFL Development League until it was disbanded in 2018. They won the last edition of the SFL competition and the first under the SPL, but they only won it once more (in
2014–15). From 2015 onwards, it has been possible for the Aberdeen Academy to participate in the
UEFA Youth League by the under-17/under-18 side winning the previous season's league at that age group; however this has not yet been achieved. For the
2016-17 edition of the
Scottish Challenge Cup, under-20 teams (later under-21) of clubs in the
Premiership were granted entry to compete against adult teams for the first time in the modern era. Aberdeen U20 won their opening round against
Formartine United of the
Highland League but lost in the next round to
Forfar Athletic of the
fourth tier. ==Facilities==
