Auston Trusty, born on 12 August 1998 (age 27), is an American central defender at Celtic. A commanding 6ft 3in (1.91m), he joined from Sheffield United in August 2024 for around £6m, a fee that made clear he was not being brought in as padding for the squad.
Before Celtic, his most productive league season came at Birmingham City in 2022–23, when he scored four goals in 44 appearances. That spell showed a defender capable of handling regular football rather than merely looking the part, which is not always the same thing.
Trusty has remained a regular first-team presence in 2025–26. He has made 26 league appearances, along with three in the League Cup, three in the Scottish Cup, one in Champions League qualifying and seven in the Europa League, where he has scored twice. His current market value is around £5m, according to Transfermarkt.
His Celtic career is still taking shape, but the outline is plain enough: a tall left-sided centre-back signed from English football for a sizeable fee, now carrying a steady workload across domestic and European matches.
