Sir Alex Ferguson, probably over a glass (or two) of vintage red wine, unholstered his larger weaponry in a recent GQ Magazine interview.
Ferguson, whose temper is now made mostly of legend, dropped some serious tonnage on FIFA President Sepp Blatter, rival European club Real Madrid, and former United chairman Peter Kenyon in the interview published by The Times.
Blatter, who during the summer likened Manchester United's £150,000 contract with Cristiano Ronaldo to a form of "slavery," was the first under attack.
Ferguson said of the Swiss head of FIFA: "I think Sepp Blatter is in danger...or has reached a point now where he is being mocked within the game...Whether he is getting too old, I don't know. But things can happen to people in power.''
"All I'm saying is that, from a position of great power, he has uttered so many ridiculous statements that he is in danger of seriously damaging his credibility."
These are bold statements from a man who knows precisely where he lies in the power structure of world football.
Ferguson is arguably the most successful, most respected manager in the game today. He knows he doesn't have a whole lot to lose as he plans to retire within the coming years.
His behaviour is like a president on the way out of office, except instead of pardoning offenders willy-nilly, Ferguson lambastes them with complete abandon.
Ferguson then beset Real Madrid's purchase of Gabriel Heinze as part ruse: "I knew what they were doing," he scoffed. "I don't believe they were interested in Heinze—good player though he is. The end game was to get Ronaldo."
Ferguson also targeted former United executive Peter Kenyon with no uncertain language: "Peter Kenyon? He wasn't a loss. The best thing that has happened recently has been David Gill.''
Kenyon was shown wearing a runners-up medal after United defeated Chelsea in the 2008 UEFA Champion's League Final, while tellingly United and world football legend Bobby Charlton did not wear winners medals, stating humbly: "This is the player's night."
Ferguson didn't let that contrast in character go unmentioned. Nor did he, apparently, let much else that was bothering him stay harboured inside his fiery belly.
A man with the experience, knowledge, connections, and intelligence of Ferguson is surely someone you don't want to cross politically.
And when he has nothing left to prove, and nothing left to lose, you might as well just keep your hatch shut.
Blathering at such a man is surely unbecoming to your career, Sepp Blatter.
