Robbie Deas, born on 27 February 2000 (age 26), is a Scottish central defender whose senior career has moved from Celtic’s system to a settled role at Kilmarnock.
He left Celtic in August 2020 for Inverness Caledonian Thistle, after the sort of early loan experience that often decides whether a young defender is ready for regular senior football or merely looks tidy in development games. Inverness gave him the next step, away from the protected environment of Lennoxtown.
Kilmarnock has since become the main part of his career. Wearing squad number six, Deas has made 98 league appearances across four seasons, scoring four league goals. That is where his work has been most visible and most sustained: a regular centre-back rather than a passing name on a squad list.
His 2025-26 season underlines that standing. Deas made 36 league appearances and scored twice, his most productive league campaign, while also featuring once in the League Cup and once in the Scottish Cup. Across all competitions for Kilmarnock that season, he made 38 appearances and scored two goals.
Deas’s career is still centred on week-to-week Premiership football with Kilmarnock. Celtic was the starting point, Inverness the bridge, and Rugby Park has been the place where he has built a proper first-team profile.
