Dundee boss James McPake has bolstered to his backroom staff with the addition of Dave Mackay as first-team coach and head of opposition analysis.
The 38-year-old began his career with the Dark Blues and appeared over 100 times for the club, including in the 2003 Scottish Cup Final.
He then moved to Oxford and Livingston, where he played in the same team as McPake.
Mackay subsequently joined St Johnstone and captained the club to their Scottish Cup triumph over Dundee United in 2014.
After having to retire through injury, Mackay, who is a UEFA Pro Licence holder, moved into management with Stirling Albion and most recently has been working with his former Saints boss Derek McInnes at Aberdeen providing opposition analysis.
McPake said: “Dave is someone I’ve known for 15 years and I’m delighted to finally get it over the line and bring him back to the club.
“I see this role as another key aspect of how we are trying to structure the football department.
“When Dave was manager at Stirling I saw a lot of his sessions and we completed the Pro Licence course together so I know what qualities he has as a coach and how he is as a person.
“His qualities and his character fit the bill for what we need at this football club.
“Dave is someone that I class as important as Jimmy Nicholl and Andy O’Boyle to aid my development as a manager.
“In this newly created role, Dave will spend time analysing the opposition and on the training pitch as a key part of my backroom staff.”
