It will come as no surprise to learn that the fallout from the launch of Sir Alex Ferguson's updated autobiography dominates the newspapers on Wednesday.
Keane was granted an immediate opportunity to hit back in his role as a television analyst ahead of the Champions League tie between Arsenal and Borussia Dortmund.
Who else is making the headlines on Wednesday? Read on to find out more.
Former Manchester United manager Sir Alex Ferguson took aim at Roy Keane, David Beckham and Rafa Benitez, among others, as he launched his updated autobiography.
Ferguson claims he could not keep Keane at the club after the midfielder criticised younger players in an interview with the club's own television channel, MUTV, reports John Cross of the Daily Mirror.
Keane hit back in his role as a television analyst ahead of a Champions League game at the Emirates Stadium between Arsenal and Borussia Dortmund. Per the same article:
I remember having conversations with [Ferguson] about loyalty. In my opinion he doesn't know the meaning of the word.
To constantly criticise other players that brought him success... I won't be losing any sleep over it.
Glenn Moore of The Independent says Kieran Richardson, Darren Fletcher and Rio Ferdinand were criticised by Keane in that interview.
Ferguson also claimed Beckham was more interested in fame than football, reports Paul Brown of the Daily Star.
Meanwhile, former Liverpool manager Benitez was branded "a control freak" by Ferguson, reports Matthew Dunn of the Daily Express.
Ben Curtis of the Daily Mirror has provided a rundown of Ferguson's quotes during the press conference and in his book.
Football writers across the media watched the press conference with Ferguson and gave their opinion on the former United manager's words.
Oliver Holt of the Daily Mirror offered an almost poignant view on Ferguson at the press conference, claiming the power had gone from the former United boss:
The reason that he appeared diminished was a lot simpler: The power had gone.
The authority had left him. The zeitgeist was elsewhere. He is an ex-manager now.
One of the books written about him was called The Boss and however seamlessly he has moved on with his life, he can no longer be that any more.
So, as Sir Alex fielded questions from reporters representing China, Israel, Norway and Australia, he fought for relevance.
Martin Samuel of the Daily Mail claimed that the book is one from a company man and not the shop floor.
The most surprising revelation at the launch was that Ferguson first cleared the contents of his autobiography with the club.
‘Of course,’ was his reply when asked whether it had the approval of United.
This was Ferguson the director, the ambassador, the lecturer at Harvard Business School speaking. He wasn’t about to alienate those around him with awkward, embarrassing revelations.
Paul Hayward of the Daily Telegraph was the ghost writer on the book, and offered his insight into Ferguson during its compilation.
Richard Beech of the Daily Mirror deserves credit for his Fergie Quiz, which asks readers to put the right rant to the correct recipient.
Real Madrid star Cristiano Ronaldo has told Bernabeu supporters to stop criticising Gareth Bale following his world-record move from Tottenham, reports Chris Richards of the Daily Mirror.
The Wales international scored on his debut for Real, but has struggled with injury in recent weeks, and the former Manchester United man has urged fans to get behind Bale:
People are putting a lot of pressure on him (Bale) because of what he cost and all that but I don't think it's good for him.
If you want to try to help him don't put too much pressure on him … leave him alone.
He hasn't had it easy because his pre-season was disrupted and then he got the injury.
If you talk to him you can tell he is very excited about playing and being part of the team.
I am 100 per cent sure he will be great for the team because he is a fantastic player and a wonderful person.
He always wants to learn, which is the most important thing.
