DUBAI: British billionaire Jim Ratcliffe is interested in buying Manchester United, a source familiar with the matter told Reuters after Elon Musk said his plan to buy the Premier League club was all part of “a long-running joke.”Musk, the world’s richest person, said on Tuesday night on Twitter that he wanted to buy England’s most successful club before clarifying that it was a joke and that he had no interest in purchasing any sports teams.The club’s owners, the American Glazer family, are under pressure with United sitting bottom of the Premier League after two games of the season. Bloomberg reported they would consider selling a minority stake, opening the door for Ratcliffe.A source close to Ratcliffe said the billionaire was a potential buyer as he wants to help rebuild the team. The Times first reported Ratcliffe’s interest on Wednesday.It is unclear if the interest would result in any deals. The Glazer family is not ready to concede the controlling stake in Manchester United and has an expectation of valuing the club at more than double its current market cap of $2.2 billion, another source said.In May 2022, Chelsea Football Club was sold to a consortium led by an investment group led by Todd Boehly and Clearlake Capital for $3.2 billion (2.5 billion pounds).The Glazers have been the target of intense criticism for their failure to invest in the team who have not won a trophy in five years. United’s net debt had grown 11 percent to about 496 million pounds ($598 million) by the end of March.The owners have also been criticized for not improving the Old Trafford stadium, the biggest club ground in the country with a capacity of around 75,000 fans.Ratcliffe, head of chemical company INEOS, is from the Manchester area and a long-standing United fan.Ratcliffe failed this year in an attempt to buy London club Chelsea which was ultimately bought by an investment group led by Todd Boehly and Clearlake Capital.United finished sixth last season in their worst Premier League campaign with respect to points earned, failing to qualify for the lucrative European Champions League.They won the last of their record 20 top-flight league titles in 2013, the year Alex Ferguson stepped down as manager after more than 26 years in charge.The club hired manager Erik ten Hag from Ajax Amsterdam in a bid to turn around their fortunes but the Dutchman has not yet succeeded in imposing his playing style, with United losing their opening two games after conceding six goals.United play their arch-rivals Liverpool, who scored nine times without reply in their two league meetings last season, at Old Trafford on Monday.Shares of Manchester United jumped 6.96 percent on Wednesday.
