It was personal. It was nasty. And it says a lot more about the writer than the object of his derision.
Rio Ferdinand's attack on David Moyes over his year with Manchester United will have satisfied those pockets of support who enjoyed the ridicule that swirled around the Scot. But it also exposed what he had inherited from Sir Alex Ferguson: an obstructive, ageing leadership group, unwilling to consider change.
Further confirmation has come this summer. For all the whingeing from Ferdinand in his new book, '#2Sides', many of the big decisions made last season have been backed by the new gaffer.
There was no rethink from Louis van Gaal about jettisoning Ferdinand and he's made the same assessment as Moyes did on the United clique, with Danny Welbeck, Tom Cleverley, Nani, Wilfried Zaha and Shinji Kagawa all moved on.
Then there's Wayne Rooney, whose revival at United is owed solely to Moyes. But even the rebuilding of this relationship drew criticism from the senior group, with complaints of Moyes 'playing favourites' making their way to the national press last season.
Yet, it was Rooney who Van Gaal went for as club captain - even ahead of his Holland World Cup skipper Robin van Persie.
For Ferdinand, Moyes' tactics and match preparation were "amateurish" and "embarrassing".
So how does that go down with the likes of Duncan Ferguson, Thomas Gravesen and Tim Cahill? Lads, you played your best football under Moyes at Everton. But this was only because your game suited the "amateurish" Moyes. Your football simply wouldn't be able to handle the sophistication of what was required at Manchester United...
It's some claim inferred by Ferdinand and goes to the heart of what happened last season. United's senior players felt superior to Moyes and above what was being asked from them. There was scant willingness to compromise and no appreciation of the approach Moyes had made.
From the reaction of the club this summer, that was Moyes' biggest downfall. He actually went into the job respecting the senior leadership, believing their press that several of them of were genuine, selfless managers-in-waiting. He thought he could lean on them to move the club through a difficult transition.
In contrast, Van Gaal, fresh from the World Cup, simply went 'whoosh'. There were no second chances. No compromise. The team wasn't good enough. The squad wasn't deep enough. And there was going to be no sentiment shown to the surly.
The one departure the Dutchman had fought to hold onto, Patrice Evra, could teach a thing or two to Ferdinand about club loyalty. It's no secret Evra had his disagreements with Moyes, but the Frenchman also had a good working relationship with his manager. It was Evra who pushed Moyes to follow through on Luke Shaw as he felt his game was slipping without genuine competition driving him on.
Now with Juventus, Evra could easily have lashed out at Moyes. After eight years with the club, he'd have done so 100 per cent confident of the backing of United's supporters. But he's kept his own counsel. There's never been a hint of dissent. Not on social media, nor through the press.
Commenting on Ferdinand's attack last week, the Manchester Evening News said it was a "classic case of history being written by the winners". But don't write off the Scot just yet.
Moyes is a good football man and highly respected in the game. And after the way he was treated by United, there's a lot of goodwill and hope within football that he can find the job that allows him to restore his reputation.
Ferdinand has stated he wants to coach once he hangs up his boots, comparing himself with Pep Guardiola 'boom' in the process.
But you fancy, given his current role on the box, over the next ten years (so long as viewers can endure the ego), he'll be talking a helluva lot more about David Moyes than his old manager will be talking about him.
