Former Manchester United star Ryan Giggs has revealed an aspect of what made Sir Alex Ferguson as successful as he was during his managerial career.
The United assistant was speaking to BBC Sport, and discussed how his former boss could tell if a player needed an arm around the shoulder or to lose his temper.
The Scottish tactician spent 26 years at Old Trafford and won 38 trophies during his reign at the club as he established himself as one of the greatest managers in football of all time.
Amongst his haul of trophies were 13 Premier League titles, two Champions League triumphs and five FA Cups, but his ability to rebuild his squad over and over again so successfully was arguably the most impressive aspect of his tenure.
With David Moyes and Louis van Gaal struggling to reach those heady heights since his retirement, it remains to be seen how long it takes before United are able to reach that level of success again.
Giggs has been linked with the post in the future, while Ferguson suggested this week that the Welshman would be manager now if he had retired from playing earlier, as reported by The Telegraph.
Instead, the 41-year-old continues to learn as an assistant to Van Gaal, and United supporters will be hopeful that he will be ready to step in when the Dutchman decides to move on from Manchester.
