Video from Sir Alex Ferguson's first day as Manchester United boss
The Scot moved to Old Trafford after winning 10 major trophies at Aberdeen.
Sir Alex Ferguson moved to Manchester United with a growing pedigree in the game, arriving from Aberdeen in 1986.
He left Pittodrie after delivering 10 trophies during an eight-year spell, having succeeded Billy McNeil in 1978.
Three Scottish Premier League titles, four Scottish Cups, a Scottish League Cup and the small matter of Cup Winners' Cup success against Real Madrid, followed up by a win in the European Super Cup, marked the most successful era in the Dons' history.
Manchester United meanwhile were seeking their first top flight success since 1967, having failed to successfully replace Sir Matt Busby after his initial departure in 1969.
As our video shows, Sir Alex arrived to a modest reception from a hardy bunch of autograph hunters on his first day at United' former training base Cliff Ground, before putting his new charges through their paces.
"I'm not feeling comfortable, I must admit," he joked with journalists on the training ground. "I'll be glad when you all get out the road.
"You can't be negative in your thoughts in a job like this.
"For me to leave Aberdeen, a job for life at Aberdeen, the safest job in Britain in the sense I'd never get sacked. I've left that to come here.
"Manchester United? The biggest club in the world."
