David Turnbull

Celtic Turnbull joined Celtic on 27 August 2020, on a four-year deal. The fee of around £3 million was a club record for Motherwell.

After three substitute appearances during September, he made his first start for the club on 4 October against St Johnstone. While there was initially few opportunities in the early part of the season, on 10 December 2020 Turnbull started in a UEFA Europa League home fixture against Ligue 1 side Lille OSC. He scored his first goal for Celtic and made an assist for Christopher Jullien in a 3–2 win against the French champion in the last group stage match that season. His subsequent form in the Scottish Premiership saw him named the SPFL Player of the Month for December. Turnbull finished the 2020–21 season with ten goals and won the PFA Scotland Young Player of the Year award, proving to be a positive for Celtic in an otherwise disappointing campaign where they lost the Premiership title and failed to win a trophy.

Under new Celtic manager Ange Postecoglou, Turnbull played regularly in the first half of the 2021–22 season. On 12 August 2021, he scored twice in a 3–0 (agg 7–2) UEFA Europa League play-off win against Czech First League side FK Jablonec. Later that month, he scored a hat-trick in a 6–0 victory against St Mirren in the league. Turnbull featured as a starter in the 2021–22 Scottish League Cup final but was forced off with a hamstring injury after 27 minutes; Celtic defeated Hibernian 2–1 and he collected a winner's medal. He was an unused substitute in that season's Scottish League Cup final

Turnbull scored his first goal for the Bluebirds in a 3–1 defeat to Blackburn Rovers on 9 November 2024.

On 16 December 2025, he scored the only goal for his club in a 3–1 home defeat to Chelsea in the quarterfinals of the EFL Cup.

International career Turnbull has played at under-16, under-19 and under-20 level for Scotland. He was added to the full national squad for the first time in May 2021, ahead of the delayed UEFA Euro 2020 tournament. He made his debut on 2 June 2021 in a friendly against Netherlands, as a starter. He was selected in the squad for the Euro finals, but did not make an appearance.
