Former manager Jocky Scott has returned to Aberdeen as first team coach.
The 64-year-old joins manager Craig Brown, 72 and assistant Archie Knox, 65, giving the management team a combined age of 201.
Scott, who played for the Dons in the 1970s, co-managed them with Alex Smith between 1988 and 1991.
"Craig identified Jocky who has a fantastic reputation and we are delighted to have him on board," said chief executive Duncan Fraser.
The Pittodrie club said that Scott would chiefly work with young members of the first-team squad.
"We recognised at the start of the season that with the very high levels of young players throughout the club that an additional coaching resource would be of real benefit," added Fraser.
"This appointment will also enable Neil Cooper to dedicate 100% of his efforts on developing the U-20 squad."
As well as managing Aberdeen, Scott has spent three terms in charge of Dundee as well as managing Notts County, Dunfermline, Raith Rovers and a spell as caretaker of Hibernian.
