Mick, I would recommend you read a bit about where City’s owners got their money from.
“City Football Group owned by Abu Dhabi United Group, an investment vehicle owned by Sheikh Mansour bin Zayed al-Nahyan, the brother of the ruler of the United Arab Emirates.” – NY Times
That group is linked to the Abu Dhabi soverign wealth fund, which basically is where much of the country’s oil revenue goes.
Similar things at Chelsea – where did Abramovic’s money come from?
And Man United’s owners put the club deep into debt with their takeover – the club’s still paying for that takeover. A similar method was used in Burnley’s recent takeover.
