Adam Matthews was born in Swansea on 13 January 1992 (age 34) and came through at Cardiff City before Celtic moved for him in July 2011, paying around £200,000. Primarily a defender, he arrived young enough to develop but ready enough to be used, which is usually the part that separates a prospect from a project.
His best league return at Celtic came in 2012-13, when he scored two goals in 22 appearances. Matthews was never the loudest presence in that side, but he became a useful and trusted first-team player across his four years in Glasgow, offering pace, discipline and a decent level of assurance on the right side of defence.
In July 2015 he left Celtic for Sunderland in a deal worth around £2m. That move began a more unsettled stretch, with spells at Sunderland, Charlton Athletic, Omonia Nicosia and Shamrock Rovers. Those years gave his career a wider route than might have seemed likely when he first broke through at Cardiff and then settled quickly at Celtic.
Matthews’ career is still remembered most clearly through that Celtic spell: a young Welsh defender signed cheaply, used regularly, and sold on for a sizeable profit after contributing as a genuine first-team player rather than just passing through.
