From a 2-0 defeat at Oxford United on November 6, 1986 to a English Premier League coronation party through the streets of Manchester on May 13.
Alex Ferguson's 26-year reign at Manchester United has seen the club transformed from a sleeping giant to a relentless, trophy-winning juggernaut in both the football arena and the sports business world.
Following Wednesday's announcement that the Scot, the most successful coach in English football history, will end his Old Trafford tenure, CNN marks seven moments which have defined Ferguson's career.
Sacked by St Mirren
Ferguson's managerial career has been littered with glorious highs, but it has not been without its lows, none more so than in 1978 when Ferguson was in charge of Scottish team St Mirren.
He oversaw a remarkable upturn in St MIrren's fortunes which saw the unheralded club win the second-tier of Scottish football in 1977 with a squad which bore classic hallmarks of a Ferguson team, notably his faith in young players. That St Mirren side had an average age of just 19.
But he was unceremoniously sacked by then St Mirren chairman Willie Todd for what he described as "breaches of contract" relating to the manager's decision to join Aberdeen.
''I regret the fact Alex did not stay longer at St Mirren and I regret the circumstances of his departure, but I still believe that the club had no alternative," Todd told Scottish newspaper the Herald in May 1999.
"There were no grudges. I've met him several times at football matches since then and our relationship is quite amicable."
Aberdeen roll over Real Madrid
Ferguson was finally appointed as Aberdeen manager in June 1978 and unprecedented success followed for the Scottish club.
He broke the duopoly of Glasgow Rangers and Celtic, guiding Aberdeen to three Scottish League titles in 1980, 1984 and 1985.
However, arguably Ferguson's finest moment with Aberdeen was on the European stage.
Following a Scottish Cup triumph in 1982, Aberdeen qualified for the European Cup Winners' Cup.
Ferguson's team reached the final, with a 3-2 quarterfinal second-leg victory over Bayern Munich one of the many highlights of an impressive campaign.
In the final, held in Gothenberg on May 11, 1983, Aberdeen faced Spanish giants Real Madrid, managed by the great Alfredo Di Stefano.
The match finished in a 1-1 draw after 90 minutes, before striker John Hewitt scored the winner for Aberdeen in extra-time.
Jock Stein's death
One of the most poignant moments of Ferguson's career arrived just over a year before he was appointed to the United job.
Ferguson was part of Jock Stein's coaching staff with the Scottish national team ahead of a crucial 1986 World Cup qualifying match against Wales in Cardiff.
Scotland needed a point to reach the tournament in Mexico, which they duly acquired following a 1-1 draw.
But the match was overshadowed when Stein, the first British coach to win the European Cup with Celtic in 1967, collapsed after the final whistle.
"I grabbed for him as he started to fall," Ferguson recalled, when talking to the Daily Mail in 2012. "The medics came out of the tunnel. I held him until he was helped inside.
"When I left to speak to the press I saw Graeme Souness and he was crying. 'I think he's gone,' Graeme said. I couldn't believe it.
"When we filed on to the bus there were thousands standing outside and the quiet sadness of the atmosphere was unforgettable. The abiding memory is of a solemn silence. It was as if the king had died.
