You say this but there are no other comparisons to the men themselves. Yes Yeung and Xia have both promised great things, but what owner would take over a football club and say "Yeah, I think I'll relegate the club again and generally not give a toss".
Xia is self-made in legitimate business and has 35,000 employees under him. Yeung was a money laundering hairdresser. Any comparison is laughable.
