Even at the best of times, Roy Keane's relationship at Alex Ferguson wasn't exactly the warmest.
Things have gone downhill between the pair since Keane's acrimonious departure from Manchester United in the Winter of 2005, with Keane and Ferguson both taking shots at each other in the year's since.
While Keane has mellowed in recent years, he still has a fiery streak and can still be quite critical of Ferguson on occasion.

Today, he's best known for his punditry work on Sky Sports and his appearances on The Overlap: Stick to Football. Roy and the panel were joined by the Corkman's footballing hero this afternoon as Glen Hoddle popped into studio.
On the topic of Hoddle's days as a player-manager, the England legend spoke about how it was important for his players to be able to criticise him on the pitch without fearing repercussions when it came to squad selection.
That train of thought led to Keane remembering an occasion when Ferguson took part in an attacking drill, which ended when Keane took aim at his coach.
"Ferguson used to have a go in the box, remember Ferguson when he was old playing, and I gave him a ball and he should've got it," Keane said on Stick to Football presented by Sky Bet.
"He said I had to go in the middle, and I said 'you shouldn't be in the boxes anyway'.
"He went f*****g mad he did.
"He made us all run around the pitches remember, I was just trying to be honest with him you know what I mean."
Pure honesty from Keane, but not for the first time, it was this type of candour and openness that got him into trouble with the boss.
