Sir Alex Ferguson's eagerly awaited account of his life as Manchester United manager will be released today - and is likely to send a number of big names scampering for cover.
Around the same time as David Moyes is due to speak to the media to look ahead to United's Champions League encounter with Real Sociedad, Ferguson will be in central London, enlightening his audience about the most decorated career the game has ever known.
Ferguson has been keen to keep the contents secret.
There have been no official leaks and no serialisation ahead of five sell-out Q+A evenings, that start in Manchester next Monday and take in visits to London, his home city of Glasgow, Aberdeen, where he first made an impact, and Dublin.
However, it has been possible to piece together little snippets of information to get an idea of what is likely to be included in a read which promises to be fascinating and explosive in equal measure.
"The problem with doing a book is you have to bring in the elements and factors which in many ways either affected or determined your management decision-making," Fergusontold MUTV in a recent interview.
"Because I've been at the club such a long time and you're building team after team after team, there are areas that you can't ignore.
"Why we sold certain players like David Beckham and Ruud van Nistelrooy. You can't ignore these things because these guys were big, big figures in Manchester United's career history."
In an article on Saturday, journalist Paul Hayward, who was responsible for committingFerguson's words to print, stated: "Ferguson decided several years ago to revisit the upheavals of the past decade, and to examine how he maintained control in the face of changes in United's ownership, the rise of player power and the new threats posed by Roman Abramovich's Chelsea and the Middle-Eastern wealth of Manchester City."
Hayward also said Ferguson "recalls the great players he has managed", listing Roy Keane, Cristiano Ronaldo and David Beckham, and "shares his thoughts on Arsene Wenger, Jose Mourinho and Rafa Benitez".
The last name itself gives an idea of what to expect.
In both public and private, Ferguson rarely had a good word to say about former Liverpool and Chelsea boss Rafael Benitez.
He once described the Spaniard as "a baby" and will doubtless find many reasons to undermine Benitez, currently at Napoli - not least the failed attempt to prise Gabriel Heinze out of Old Trafford.
That is just one of a number of reasons to anticipate the book getting a frosty reception at Anfield.
The fall-out from the racism row that ended with Luis Suarez getting an eight-match ban for abusing Patrice Evra should be covered, and that will not reflect well on Kenny Dalglish, with whom Ferguson had previous anyway.
Although his relations with Arsenal manager Arsene Wenger eased considerably during the latter days of his Old Trafford reign, it will be interesting to see whether Ferguson touches on the Gunners' failure to secure any silverware since beating United in the 2005 FA Cup final, or the Pizzagate row from 2004.
Asked about Ferguson's book, Wenger joked: "We all fear the worst!" before adding: "I think it is good that he has made a book."
The Scot always got on well with Jose Mourinho, but the issue of whether he was considered for the succession - in which the Chelsea boss claims he was never interested, but a recent book alleges he was in tears when he found out he had been passed over - might be touched upon.
Indeed, such has been Ferguson's longevity, there could be a story at every turn.
Keane contributed so much to United's success but what fans and an expectant public really want to know is the content of that infamous MUTV interview in 2005 which got pulled from the schedules because of the damning criticisms of so many young team-mates and eventually led to the Irishman's abrupt exit.
Another cult hero, Ruud van Nistelrooy, departed amid some acrimony not long afterwards.
And then there is Beckham, the most recognisable face of English football - scarred by a boot Ferguson sent flying across the Old Trafford dressing room - and his relationship and subsequent marriage to a member of the Spice Girls.
Ferguson's last autobiography ended with the 1999 Treble, since when United have won another eight Premier League titles and appeared in three Champions League finals, winning one.
Ronaldo spent six glittering years at the club to lay claim to being one of the best players United have ever had, Ryan Giggs has moved towards 1,000 career appearances, Paul Scholes has illuminated pitches across the land.
It is hard to think of a topic on which Ferguson cannot have an opinion.
Peter Kenyon's part in failing to secure the services of Ronaldinho in 2003, and the reasons why Wesley Sneijder did not join nine years later may also feature.
The Football Association and referees are likely to provide more fertile ground for those looking for criticism than the Glazer family, for whom Ferguson has always spoken up.
And then there is Wayne Rooney.
Had Ferguson remained at Old Trafford, Rooney would surely have been shown the exit door. As it is, Ferguson will need to tiptoe round the matter carefully so as not to cause Moyes any problems.
If Moyes were in any doubt as to his status, it will be reinforced on Wednesday, whenFerguson's name, rather than his own, is plastered all over the back pages.
He may be the current Manchester United manager.
But, for sheer weight of public interest, Ferguson remains king.
