Signed from Dumbarton for £100,000 in January 1989 Steve McCahill made his Celtic debut as a sub in a 3-0 league win at Dundee on February 25 that same year.

The centre-half was part of the Celtic team which lifted the Dubai Super Cup against Liverpool on April 4th 1989.
However on April 12th he broke his jaw in a game at Motherwell and despite making a fully recovery he was never really in the first team picture again.

He played out the majority of his career as captain of the reserve team before joining Morton in October 1992.
