Auston Trusty, born on 12 August 1998 (age 28), is a United States central defender with Celtic. An imposing 6ft 3in (1.91m), he gives Celtic an obvious physical presence at the back, though the rest of his game has had to stand up to the usual Glasgow scrutiny.
Before coming to Celtic, Trusty’s most productive league season came with Birmingham City in 2022-23, when he scored four goals in 44 appearances. He later joined Sheffield United, and Celtic brought him north in August 2024 for around £6m.
His first two seasons at Celtic brought domestic reward. Trusty was part of the squad that won the Premiership in 2024-25 and 2025-26, as well as the League Cup in 2024-25. There was also a Scottish Cup runners-up finish, the sort of detail that tends to linger less pleasantly around these parts.
In 2026-27, he has made seven league appearances for Celtic, along with one League Cup appearance, four in the Scottish Cup, two in Champions League qualifying and one in the Europa League. Across those competitions, he has 15 Celtic appearances and one goal. He has also represented the United States this season, making two World Cup appearances and scoring once.
His current market value is around £5m, according to Transfermarkt. Trusty’s career has taken him from the American set-up through English football and on to Celtic, where he remains part of the defensive group.
