Twitter is 'a waste of time' - says Sir Alex Ferguson
Manchester United manager Sir Alex Ferguson has hinted that he could ban his players from using Twitter after branding the social network "a waste of time".
Earlier this week United forward and England international Wayne Rooney caused controversy after warning an abusive Twitter user that he would put him "asleep within 10 seconds" in a fight.
Rio Ferdinand is the most prolific Tweeter in the club's squad with more than a million followers, while several hundred thousand Twitter users follow his team-mate Michael Owen.
Ferguson, 69, admitted that he does not understand how Twitter works and indicated that the club is investigating whether it should be banned among players.
"I don't know why anybody can be bothered with that stuff," he said.
"How do you find the time to do that? There are a million things you can do in your life without that. Get yourself down to the library and read a book. Seriously. It is a waste of time.
"It seems to have a certain momentum at the moment. Everyone seems to want to do it."
Several footballers have already found themselves reprimanded by the Football Association for comments made on Twitter.
West Ham's Carlton Cole and Danny Gabbidon were fined for Twitter comments while former Liverpool winger Ryan Babel landed himself in hot water after posting a mocked up picture of referee Howard Webb in a Manchester United shirt.
