Leicester have confounded all expectations this season and, following Saturday's 3-0 victory at Swansea City, sit top of the Premier League after 15 games.
That win at the Liberty Stadium came courtesy of a Mahrez hat-trick, with the Algerian and Vardy - who leads the Premier League scoring charts - the stars of the show so far this season at the King Power Stadium.
"When Aberdeen won the European Cup Winners' Cup [under Ferguson], it was the greatest moment for Aberdeen in their history and it was the worst moment too," Ferguson explained at the TechCrunch Disrupt London event.
"Five players left within a year; Gordon Strachan went to Manchester United, Mark McGhee went to Hamburg.
"Leicester may have a situation where some players love being there and don't want to move and they will have some who do want to move to Manchester United, or Liverpool or Real Madrid. It is natural, it is progress."
