Manchester United boss Sir Alex Ferguson blames the media for the increased sack culture in England. An increasingly short-term view of the world stems, in Ferguson's opinion, from a changing media landscape, which lends itself to sensationalism, triggering fear and panic amongst supporters and club officials.
"I judge my success by trophies,' he told US-based satellite radio broadcaster Sirius XM. "We have a good record of that and a good history too.
"We are very ambitious to maintain that success. We know we have to perform to make sure we are always up there."
He added: "It is not healthy being a manager these days. It is a results industry generated by a really aggressive press.
"The nature of the fans and owners have changed. Time is of the essence.
"You can fulfil all your ideas and philosophies about how a team is run and how they play."
