The Scot took charge of his final game as manager of Manchester United on Sunday as his Premier League champions were held to a thrilling 5-5 draw by West Brom at the Hawthorns.
"You’ve been fantastic servants to me. We’ve achieved some great things," Ferguson told his players, reports The Sun.
"And if all that we’ve done together means anything to you, there’s just one thing I’d ask of you all.
"After I’ve gone and we bump into each other, I don’t want to hear you call me Boss ever again.
"Call me anything but that. Call me whatever you’ve called me behind my back for years — but just not Boss.
"You’ll have a new boss by then and he’s the only one you should call that."
