I think you need to be carful that you don’t fall into the trap of our detractors.The OP asked if a particular reference to the Middle Eastern owners was racist. It wasn't, and it's a fairly straightforward argument why.
The fact that the two clubs in the PL with Middle Eastern owners have so much more wealth, power, and influence over a huge number of companies, is factual. It is absolutely vast in comparison to any other owners, who are already some of the wealthiest individuals around. It's therefore a legitimate concern for the PL, that currently only applies to the two Middle East owned clubs. Describing them as such is factual, not racist.
If you want to accuse someone of racism, then stick to incidents which are clearly racist, of which there are plenty. Don't give them an easy argument by overstretching.
It reminds me of a lecturer I had at University. He worked with Government ministers, and said that if they didn't want to do something, they would never try to challenge the hard argument. They'd pick up on something easy, and say 'if you got that wrong, then the rest of your argument is probably rubbish too'.
We are not invested in by a state or or state company, or sovereign wealth fund.
I wouldn’t be surprised if Silverlake or Todd at Chelsea have more invested in / control / influence more companies than Sheik. Khaldoon as high up at Mabuala excuse the spelling. Would be another.
The sheik does however perhaps have the most connections of anyone but a lot of that politics. And even in business how many will do he a favor to the level required to be an issue e.i sponsors over what would be fair. Connections only get you so far. You need a good offer legitimate offer a side offer deal off the books or control via shares. There is also a limit to how many sponsors anyone can get especially at the high end. 1 shirt sponsor but maybe a banking partner per region. The sheik could get 1000 mates to agree to sponsor us but if they pay market rates or clash with existing sponsors it doesn’t make any difference
