There's no doubt that there are a lot more corrupt individuals inside the FIFA council, they are like elites on their own which makes them hard to touch if there are no concrete evidence that points towards them. We may have no solid proof about it but we can actually say that there are miracles happening behind the scenes but at one point, we cannot really blame them as there will be no miracles if countries that are so eager to host a World Cup will just take the process fairly without using their connections and money.
Yes, the only reason why they are difficult to touch is because there is no authentic evidence that can be used to touch them even deeper. However, the name of a crime will gradually be revealed, as for example what happened recently which ended with the dismissal of the FIFA CEO. Something like this would definitely smell no matter how well they hid it. Because when their CEO did it, it would be very doubtful if the other members did not know about and feel the bribes they received.
But one of the reasons why Qatar World Cup will go down in history is that Qatar has spent a lot of money to build the World Cup stadiums. The stadiums that look beautiful and eye-popping. But I don't think any other country can host such a big World Cup. But yes, it is expected that we will see some new arrangements.
True, Qatar prepared very well and they spent a lot of money to make the World Cup a success. In terms of finances there is no doubt for Qatar because they have a lot of budget. They are serious about being the host, even with the problems that occur which I think are very common things on a very big stage like the World Cup which is the biggest party of the world's footballers.
