The American wealth magazine put the Red Devils at the top of their latest list of the world's richest football clubs, with an estimated value of £1.2 billion.
And that leaves United flying high at the top of the sporting tree, ahead of the NFL's top team the Dallas Cowboys (£1.072 billion), and baseball's number one club the New York Yankees (£1.040 billion).
Spanish giants Real Madrid are second on the list of top football clubs at £859m, with Arsenal third on £767m.
European and Spanish champions Barcelona are fourth on £650m, but are the only debt-free side in a top six that is rounded out by Bayern Munich and Liverpool.
Chelsea have slipped behind Juventus to ninth on the list after posting losses of nearly £50 million - the worst financial performance of any club in the top 20 - while Newcastle cling on to their place in the top 20 despite their relegation at the end of last season.
