UEFA president Michel Platini is launching a new attack on Premiership clubs ahead of tonight's Champions League final.
But UEFA president Platini reckons their success is unfair for clubs who compete within their means.
European football's governing body is bringing in a licensing system that will see clubs who do not balance their books banned from competition.
Platini said: "It's clear the more in debt you are, the greater the chance you have of winning. It's not very ethical for our sport.
''We have to start thinking how we can ensure respect for the clubs who don't have debts and who never win any more because they don't have these budgets."
Chelsea reported a loss of over £100million for each of Roman Abramovich's five years as owner, while United have debts close to £800m.
