Sir Alex Ferguson spent 26 years in charge of Manchester United, from 1986 to 2013. In that time he won: 13 Premier Leagues; 5 FA Cups; 4 League Cups; 10 Community Shields and; the Champions League twice.
Manchester United’s legendary manager did not win the Premier League in his first 6 season with the Red Devils, but after that, he only missed out on 7 Premier League titles, winning 13 overall.
The Scot says that changing the manager will not necessarily bring success, but consistency does.
Ferguson sites other great managers who have spent long terms with Premier League clubs such as Arsène Wenger, who has won 3 Premier Leagues, 6 FA Cups and, is regularly qualifying for the Champions League with Arsenal over his 19 years of service.
Sir Alex has also used Nottingham Forest’s legendary manager, Brian Clough, to support his point. Clough won the European Cup twice, the League Cup four times and League One in his 18 years as manager.
Speaking to ESPN, Ferguson has stated that consistency earns success:
“There’s no evidence that sacking a manager gives you success,”
“But there is evidence at Manchester United, at Nottingham Forest, at Arsenal that [if] you retain the manager for long periods, you get consistency and you get success.”
Sir Alex Ferguson currently holds the role of UEFA Coaching Ambassador and lectures at Harvard University.
