Stephen Welsh was born in Coatbridge on 19 January 2000 (age 26) and joined Celtic from Greenock Morton in January 2020. A commanding 6ft 3in (1.91m) central defender, he came into the first-team picture at Celtic without much fuss, which is often the safest way for a centre-half to do it.
His most productive league season at Celtic came in 2020–21, when he made 16 appearances and scored once. He has also collected two Premiership titles, a Scottish Cup and two League Cups with the club, though his role has more often been that of a squad defender than a guaranteed starter.
Welsh moved on loan to Motherwell in January 2025 and was still getting regular senior football there in 2025–26, making 25 league appearances and scoring once. He also made one league appearance for Celtic that season, a reminder that he remains part of the wider first-team picture rather than a player entirely out of sight.
He wears squad number 57 at Celtic, and his market value is around £1.5m according to Transfermarkt. His career so far has been built around Celtic, with the Motherwell loan giving him the regular league football he was unlikely to get every week in Glasgow.
