Sir Alex Ferguson knew how to get his players going.
Take his treatment of former Manchester United forwards Wayne Rooney and Luis Nani, for example.
Fergie would shout at Rooney because he knew it would bring out the best in him, but he wouldn’t have a go at Nani because it would have an adverse affect.
It’s this level of man-management that made the Scot such a success at Old Trafford.
Man United have missed his leadership since his retirement in 2013.

The Red Devils really haven’t been the same juggernauts since.
Club legend Rio Ferdinand was there for the highs, winning six Premier League titles under Ferguson.
And he’s shared a story that shows Ferguson’s unique and outside-the-box thinking.
The legendary manager brought the 33 Chilean miners who spent two months trapped underground to Carrington to meet the players in 2010.
The miners endured 69 torrid days underground after a rockfall caused a tunnel to collapse.
All 33 miners were rescued in a story that gripped the world.
And they were invited to Manchester to meet United’s players and be guests of honour at their game against Arsenal.
Ferdinand explained the story to YouTubers Poet and Vuj.
“Do you remember the Chilean miners?” the former centre-back said.
“They started thinking about eating each other to survive. It was a real team effort to get themselves out.
“We were sitting on the bikes before training and all of a sudden these guys started walking in.
“We were saying ‘who are these guys?’.
“Ferguson comes in and says ‘do you know who they are? These are the guys that were trapped underground from Chile.’”
Ferdinand continued: “We were playing the next day. And he said ‘my team talk was yesterday’.
“‘If you can’t run around and kill yourself, almost bursting at the seams for 90 minutes, after what you saw yesterday, you don’t deserve to be here’.
And we battered the team.
An extraordinary tale that highlights the genius of Sir Alex Ferguson.
