Wigan Athletic chairman Dave Whelan believes next season will be Sir Alex Ferguson's last in charge of Manchester United. Whelan says Ferguson will retire at the end of next season due to health concerns.
The Wigan chairman, who is a close friend of the United boss, told ESPN: "After next season, Sir Alex will call it a day. The pressure is telling, especially when you are at the top for so long.
"The older you get the harder it is to cope with all that pressure and eventually it will affect you.
"Sir Alex is resilient and I know he will want to carry on until he drops and I respect what he has achieved."
Last Friday Ferguson suffered a minor health scare when he was taken to hospital after suffering a nosebleed that would not stop.
Whelan added: "I am sure his intention was to carry on for two or three, maybe even more years, but he has had a little scare in the last week or so and that tells me he will think very hard and realise there is no point trying to carry on for another five years and take the risk."
