David Turnbull, born in Carluke on 10 July 1999 (age 27), first made his mark at Motherwell. His 2018-19 league season remains the obvious early marker: 15 goals in 30 appearances from midfield, enough to make him one of the more interesting Scottish players outside Celtic at the time.
Celtic signed him from Motherwell in August 2020 for around £3.5m. He arrived with clear domestic pedigree rather than mystery, and became an important first-team player across a spell that brought two Premiership titles, two Scottish Cups and two League Cups. Celtic were also runners-up once in the Premiership and once in the Scottish Cup during his time at the club.
Turnbull left Celtic in February 2024, joining Cardiff City for around £2m. He is now with Cardiff as a central midfielder, wearing number 14, and has made eight Championship appearances in 2026-27.
His career has moved from a productive Motherwell breakthrough, through a trophy-winning spell at Celtic, to the Championship with Cardiff. It is a solid Scottish football career, shaped most strongly by that move to Celtic and the medals that followed.
