Keane's publishers insisted book would be well-kept secret until Thursday press launch. They're on sale at Tesco in Burnage . .

Keane's revelations so far: Ferguson - prick. Haaland - prick. Ronaldo - good looking. Bobby Charlton - light sleeper.

Absolutley living for the Roy Keane's autobiography on Thursday. Don't think I've ever been so excited for a book #Hero #Legend #keane

Couldn't possibly be more excited about the legend that is Roy Keane and his new book!!

Some people too scared to have/share/hear opinions. Thank God for straight-talkers like Roy Keane & @KP24

Don't know which one I'm more bored with, Kevin Pietersen or Roy Keane's autobiography book updates! #BoreOff #DontNeedToReadThemNow

I can think of few things more boring than another ghosted autobiography by Roy Keane. A book of all his beards would be better.

is this the first book ever launched by this method? drip-fed to the audience line by random 140-character line?

Imagine how hairy Roy Keane would be if he was trapped on a desert island?
Strike that, imagine Roy Keane not being able to LEAVE an island?

With the release of all these autobiographies, I can't help but think of Thomas Paine. 'Character is much easier kept than recovered.'

Tesco have confirmed that Roy Keane's autobiography is 86% horseshit.

“@guardian_sport: Keane: I didn’t mean to deliberately injure Haaland" ... He says, while admitting that, in fact, he did

I know everyone's bored of Keane but if you haven't read him on signing @RobbieSavage8 then do it. Via @DTguardian pic.twitter.com/kZZo6yiDnz

No mention of John Delaney by name in the book either - not sure if he would be disappointed by that or not.

— Daniel McDonnell (@McDonnellDan) October 7, 2014

Keane's book a bit staccato, but really good, and often hilarious - both intentionally and unintentionally. Much more than headlines.
