A player with an aggressive attitude to the game but with a skilful left foot. A hard-tackling and aggressive ball winner the red-haired Galloway started his career with Berwick and after spells at Mansfield Town and Halifax he moved to Tynecastle in the autumn of 1987. Galloway’s combatative performances for Hearts were a key reason why the Edinburgh side were able to push Celtic all the way during the 1987/88 season.
Bhoys boss Billy McNeill turned to Galloway to add steel to his side and Mike would make his competitive debut in a 3-1 win at old club Hearts on August 12. He would be a regular feature in that first year with the club and despite a weight problem and some inconsistent performances which saw him in and out of the team he would earn a Scotland cap in October 1991.
On his game he was an excellent midfield enforcer but at other times his slackness could be costly and as managers came and went at Parkhead a lack of discipline off the field saw Galloway lambasted by boss Lou Macari over missed training sessions.
From that time on he was seldom more than a bit part player at Celtic Park and he eventually departed in 1995 for Leicester City. Serious injuries sustained in a car crash would end his football career.
