I enjoy him saying it wouldn't happen, but if it did happen it would be Man Utd, which would cost several billion and is loaded with debt.
Looked at his twitter, found this gem in which he says they wouldn't make money investing in a football club (they absolutely would if they grew a club into a commercial success like Liverpool and Spurs), and that they would only invest in money spinners like...Uber, which lost $8+ billion last year. He also ends with saying this would only happen if there were real estate investments to be had, too, which is seemingly why the Reubens are involved
Maybe he's right, I don't personally think we'll be takenover, but his opinions have plenty of holes in them.
