In a global study carried out by research agency Kantar Media, 54,000 respondents from 39 countries were quizzed on which team they supported. From the data, Kantar found that United has as many as 659 million supporters spread out across the globe.
Richard Arnold, the club's commercial director, believes the findings demonstrate the value of the United brand and the history surrounding the Premier League's most successful team.
On the club's official website, Arnold said: "Manchester United has built on a tradition of iconic teams and iconic achievements - Beckham, Busby, Benfica '68. Now our games are broadcast to 1.15 billion households globally, to an audience of over four billion a year."
