Old Trafford has not had much to laugh about recently
The Old Trafford boss said, in an exclusive BBC Sport interview, he was not talking to the written media in England because he no longer "trusts the press".
Ferguson said the press were printing misleading stories that he had clashed with Keane about deploying his captain in the centre of defence during Saturday's 3-0 defeat to Chelsea.
"This is what you're seeing all the time. Roy is perfectly happy here. He loves it here. These are the best moments of his life."
Ferguson, whose tenure at Old Trafford ends at the end of the season, said he had lost faith in the print media.
"I had a press conference a couple of weeks ago and when I read what I was supposed to have said I was staggered," Ferguson told Sport on Five.
"I couldn't believe the quotes and headlines they used.
"What's the point of doing a press conference if they are just going to tell a pack of lies?
"So I just don't see the point of it to be honest. "
Competition between newspapers and journalists has led to a deterioration in editorial standards added Ferguson.
"It's got worse and worse, definitely without question and I don't know where it's going to end.
"I can't trust any of them.
"There are some excellent journalists, honest journalists, and respected journalists.
"But in the present situation you've got young people coming into the game and editors telling them what to do and put spin on things.
"You're up against a competitive animal, where they're all competing for headline news.
"It's impossible to change it," he said.
United are currently eighth in the Premiership and have lost five games in the league already this season.
And Ferguson says that that stuttering start to the season has given newspapers and journalists "a field day".
"We've been successful for the last nine years and they've not had that opportunity to have their tuppence worth," added the United manager.
Takeover speculation
Meanwhile on Tuesday British bookmakers William Hill cut the odds on Middlesbrough manager Steve McClaren succeeding Ferguson.
McClaren is now third favourite at 4-1 after punters forced his odds down from 20-1.
"Between 11.33 and 11.36 this morning we took 14 bets of up to £100 pounds a time for McClaren to succeed Ferguson from telephone punters in Manchester, Blackburn, York, London and Liverpool," said William Hill spokesman Graham Sharpe.
William Hill make England coach Sven-Goran Eriksson 6-4 favourite for the United job with Celtic's Martin O'Neill second at 5-2.
United has been at the heart of takeover speculation.
And Irish racing magnates JP McManus and John Magnier - close associates of Ferguson - have built up a stake in United.
Their Cubic Expression Company now owns a 8.65% stake, second only to BSkyB's 9.9%.
"We can only assume that conspiracy theorists believe that friends of Fergie may be poised for a takeover which would clear the way for McClaren to return," said Sharpe.
