'He'll regret it': The day Alex Ferguson quit Aberdeen for Man Utd
Alex Ferguson and Archie Knox led Aberdeen to victory in the UEFA Cup Winners Cup in 1983
When Alex Ferguson announced he was joining Manchester United after eight trophy-laden years at Aberdeen, there was shock among fans.
They had seen the legendary manager lead the Dons to three league titles, four Scottish Cups, the Cup Winners' Cup and the UEFA Super Cup.
One told BBC Scotland News at the time: "I think he's making the wrong move, I think he will regret it."
Ferguson went on to become one of the most successful football managers in history, winning 38 trophies during a 26-year tenure at Old Trafford.
On the 40th anniversary of Ferguson's decision to leave Aberdeen, some of those at the centre of the events have been reflecting on the day.

He had been tasked by his editor to head to Aberdeen to find out more about rumours that the Dons boss was in talks with Manchester United.
The flight he boarded in Glasgow was filled with journalists - but most were heading north to cover the Chinook helicopter disaster in Shetland in which 43 people died.
