Liam Donnelly, a consummate midfielder, was born on 7 March 1996 in Northern Ireland. With his current age clocking in at 30, he primarily assumes the role of a central defensive midfielder for St Mirren. He stands at an impressive height of 5ft 11in (1.81m) and carries a robust weight of 12st 6lb (79kg). When on the field, he can usually be spotted bearing the number 44 jersey.
In July 2011, Donnelly marked his debut in professional football when he joined Dungannon Swifts in the Northern Irish Premiership. During his inaugural 2011-2012 season at Dungannon Swifts, Donnelly was plunged into the fervour of seven first team league matches. A year later, in July 2012, Donnelly took his first international leap by transferring to Fulham in the English Premier League for an undisclosed fee.
Following three years at Fulham, Donnelly sought greener pastures in July 2015 by transferring on loan to Crawley Town in England's League Two. In his spell with the then League Two side, Donnelly appeared ten times in the 2015-2016 season.
Another stint kept Donnelly within England's football circuit. In August 2016, he severed his ties with Fulham and relocated from the English Premier League to Hartlepool United in the English National League. Donnelly quickly integrated into the line-up, summiting to 32 first team appearances in the 2016-2017 season, followed by 22 appearances and two goals in the 2017-2018 season.
The sands of time brought Donnelly back to his Celtic roots in July 2018, transferring from Hartlepool United to Motherwell in the Scottish Premiership. His journey with Motherwell spanned from the 2018-2019 season to the 2021-2022 season. In that duration, he evidenced his increasing proficiency, hitting seven first team appearances and one goal in the first season, scaling up to 22 appearances and seven goals in the second, followed by one appearance in the third, before rounding off his time with 23 appearances in his final season with Motherwell.
Riding the wave of his career, in July 2022, Donnelly switched from Motherwell to Kilmarnock, both in the Scottish Premiership. Over his three seasons with Kilmarnock, he made 74 first-team appearances, finding the back of the net thrice.
Most recently, in July 2025, Donnelly transferred from Kilmarnock to St Mirren, securing another season in the Scottish Premiership. In the ongoing 2025-2026 season, Donnelly has made 15 appearances and scored one goal. He further registered his participation in the League Cup 2025 - 2026 for St Mirren with two appearances as a substitute and echoed this performance in the Scottish Cup 2025 - 2026 for St Mirren, again appearing twice as a substitute.
