British billionaire Jim Ratcliffe already has interests in football, Formula One and cycling. He now owns a slice of his boyhood club, Manchester United. It was announced on Sunday that the founder of chemicals giant INEOS had bought a 25 percent stake in the Premier League giants after a protracted saga. INEOS joined the race to buy United early this year after the club's owners, the Glazer family, said they were willing to listen to offers. United fan Ratcliffe, who made an unsuccessful bid to buy Chelsea last year, has long been linked with the Old Trafford club.
