Money =/= power
Qataris have money and they can pay/bribe people to get what they want. Perez has well established connections all over the Europe and possible world. Of course he also has money that helped him on his way to where he is today but now he has other things that Qataris will never have. IF Perez/RM seriously goes head to head against Qataris/PSG in any issue I'll bet on him coming out as a winner every time. I'm not talking strictly about football transfers here because it's clear that the likes of PSG and City can overpay for almost everyone they want but there is a lot more than just that that makes clubs great and poweful. That's why RM will always stay way ahead of PSG and other oil money clubs, at least until Perez will be their president. If they get another Calderon after he dies (I believe he'll stay a president until his last days and I totally expect him to live 100 years and Qatar will run out of money/oil long before that) then it's possible things will change but until then Qataris don't stand a chance against him.
You are very deluded if you think that Perez has more power that One of most rich States in the world
Which controls among the largest oil and gas fields in the world, and has powerful friends like the USA and France.
Qatar is more powerful that the same Spain.
Perez is no one, a little shit in the midst of so many big beasts.
Perez's only advantage is that Psg is just a toy for Qatar.
Perez is such a great boss that Was forced by the Arabs to remove the cross from the logo of Real Madrid in these country
