Roy Keane is never one to hide his true feelings.
As a player, the Irishman was ruthlessly brilliant, excelling as captain of Manchester United under Sir Alex Ferguson.
He was a leader of men who always set the example with his quality and as such, he demanded the best of those around him.
But back in 2005, his fiery nature contributed to his departure from United, with Keane's contract terminated by mutual consent in November of that year.
One of the key factors in the debacle was an interview the Irishman gave to MUTV after United lost 4-1 against Middlesbrough.
Keane was openly critical of John O'Shea, Darren Fletcher, Kieran Richardson and Alan Smith, while he also made his feelings about Rio Ferdinand abundantly clear.
The Irishman said of the club's then record signing: "Just because you are paid £120,000-a-week and play well for 20 minutes against Tottenham, you think you are a superstar."
The Englishman was on the club's books at the time and in his latest Sunday Times column, Rooney says he agreed with Keane's assessments.
"I was at United when he gave his infamous MUTV interview but disagree with how it’s portrayed," the Derby County star wrote in his Sunday Times column .
"Roy was supposedly too critical of his team-mates but I’ve watched the video and there’s nothing wrong with it at all.
"He said that players can’t pass the ball ten yards and they’re playing for Manchester United and it’s not good enough. Well, he’s right.
"Now Roy Keane was vocal. He had an aura. I remember my first United training session thinking, 'I need to impress him.' Not the manager. Him."
Ferguson said Keane had "overstepped the mark" when he decided to play pundit some 15 years ago, but that's just the kind of player he was and in reality, the decision to put him in that interview situation is what needs questioning the most.
He was always honest, regardless of whether feelings were going to be hurt, a tad similar to Michael Jordan in Netflix's brilliant documentary 'The Last Dance'.
But in the world of sport, honesty sometimes isn't the best policy...
