Glenavon

Glenavon was the first provincial club to win the Irish League title (1951–52) and also the first provincial club to do the league and cup double (1956–57). The latter triumph also made them the first Northern Irish team to enter the European Cup. Glenavon has had a number of talented and famous players, none more so than Wilbur Cush and Jimmy Jones, who were to the fore in "the glory years" of the Fifties. The success of the 1950s is still the benchmark at the club – the closest the club have come to achieving a league success since came in the 1993–94 season, when but for two late goals in the final match Glenavon would have been crowned champions.

Glenavon enjoyed a good run throughout the 1990s, consistently achieving good placings in the league and winning several cup competitions, including Irish Cup wins in 1991–92 and 1996–97, and were runners-up against Glentoran in the 1995–96 and 1997–98 editions of the cup. The club then suffered a relatively poor spell during the early 2000s, which culminated in relegation to the second tier in the 2003–04 Irish League season. Although they were promoted the following season, Glenavon continued to struggle towards the bottom of the league throughout the remainder of the decade, going through several managers such as Terry Cochrane, Stephen McBride & Marty Quinn. McBride was a Northern Ireland international and a popular Glenavon player in the 1980s & 1990s, but his reign lasted just seven months before he was relieved of his managerial duties with Glenavon at the bottom of the IFA Premiership.

Former Portadown & Glentoran forward Gary Hamilton was appointed player-manager in December 2011, managing to steer the club from relegation in the remainder of the 2011–12 Irish League season. This was followed up by a 9th-place finish in the 2012–13 season. The 2013–14 season was welcomed by many as a successful season, the Lurgan club securing a top-six league finish and a return to winning major silverware with the 2013–14 Irish Cup, in which Glenavon triumphed 2–1 over Ballymena United in the final.

Following on from this cup triumph was a successful 2014–15 season. Though Glenavon did not fare as well in the Irish Cup, exiting at the 6th round to Championship 1 side Harland & Wolff Welders, an excellent late run of 7 consecutive wins saw the Lurgan Blues pip their Mid-Ulster rivals Portadown to a third-placed league finish, therefore sealing European football for the 2015–16 season.

The 2015–16 season would be another good season for the Lurgan Blues, once again securing Europe on the penultimate matchday by finishing third, on a points total of 69. Even more success was to follow, as the club claimed a second Irish Cup win in three years, defeating David Healy's Linfield 2–0 in the final.

Glenavon did not enjoy similar success in the 2016–17 season. Despite having signed former Celtic and Northern Ireland winger Paddy McCourt, the club struggled for form and could only achieve a disappointing 6th-placed finish in the league. Although the club reached the semi-finals of the Mid-Ulster Cup, League Cup and Irish Cup, they were defeated in all by Warrenpoint Town, Carrick Rangers and Coleraine respectively. Glenavon also suffered agonising defeat to Ballymena United in the Europa League playoff final, therefore missing out on a fourth successive year of European qualification.

Despite failure to qualify for Europe and a large exodus of players at the start of the 2017–18 season, the signing of players such as Sammy Clingan and Andrew Mitchell, aligned with the emergence of Bobby Burns, meant that Glenavon had a resurgence in form, finishing third once again, and qualifying for Europe. However, the only piece of silverware attained was the Mid-Ulster Cup, having exited the League Cup and Irish Cup via shock defeats at the hands of Ards and Loughgall.

While the 2018–19 season yielded a club-record points total of 70, the club had a disappointing record in the major cups, falling to defeat against Dergview and Dungannon Swifts in the League Cup and Irish Cup respectively. However, the Lurgan Blues did retain the Mid-Ulster Cup with a 4–3 victory over Warrenpoint Town. Despite attaining another third-place finish, Glenavon fell to a 2–4 defeat against Glentoran in the Europa League playoff semi-final and failed to attain European qualification for the following season.

The club endured a difficult 2019–20 campaign, falling to several heavy defeats in the league and exiting the Irish Cup at the 5th round with a 2–0 defeat against Coleraine. Inconsistent form meant that the club finished outside of the league's top-six for the first time since the 2012–13 season.

The Lurgan Blues' form improved significantly in the 2020–21 season, but the club narrowly missed out on a top-six finish; their final points total of 62 was the highest points tally recorded for a team in the bottom-six. Their seventh-place finish secured the Lurgan Blues a spot in the Europa Conference League playoffs. They faced Larne in the semi-final, losing narrowly to a Martin Donnelly goal in injury time, leaving Glenavon without European qualification.

The 2021–22 season saw the unexpected departure of the previous season's top scorer, Danny Purkis, but Glenavon would once again claim a seventh-place finish and qualification for the Europa Conference League playoffs. They were defeated at the semi-final stage, losing 2-0 against third-placed Glentoran at The Oval. The same opposition had eliminated Glenavon in the Irish League Cup earlier in the season. The Lurgan Blues exited the Irish Cup in controversial fashion, having had two goals disallowed against Crusaders.

On 13 September 2023, it was announced that Gary Hamilton had vacated the post of manager, following a number of poor results at the beginning of the 2023–24 season. U20s manager Gary McAlister took over as caretaker for matches against Carrick Rangers and Crusaders, and on 25 September, former Warrenpoint Town manager Stephen McDonnell was appointed in the role on a permanent basis.
