I hope Elon Musk buys a football club like other millionaires in the world, with the power of money that Elon Musk currently has, of course it's easy to buy Manchester United, AC Milan or something else, and of course buying a football club can be a good promotion for the Tesla company so it's getting more and more popular.
I hope you do understand that there is some investment that is not a fast one to make fast profits from, there heavy challenges and needed good supervision which you were not interested in. Look at Barcelona and Juventus that has been fined for multiple charges, there all doing all that to boycott some taxes because they don't make enough to have what they want in their club. He can buy the club but is it going to be making Elon streams of income just the same way he makes in Twitter (now called X) and Space X, it is not about buying a club but will the club gives you enough money to generate to refund money borrowed? it is possible that Elon can buy any business wished but I don't think it is going be a club for now.
