United have trophies from more than a century ago, I think that was the point - not that their Fergie years were indicative of their entire history
City doesn't have a 'history' by comparison in terms of success/trophies much less support or financial strength. I am talking also about fan support and while Liverpool's success and also gone through peaks & valleys, no one would ever compare the level of support your Merseyside rivals have or have had to that of City. I can walk out my door and run into a child wearing a United or Liverpool kit before I will a City one, for example
Buffett is a money man, aka investor - he builds nothing, he trades shares like a child does their marbles or pokemon cards. You cannot compare corporate business and M&A to football's sporting side much less it's fan support - they are not linked and he certainly is not interested in that side of 'success', only the bottom line & profit sharing. So yeah, he's a money man
