I mean we should agree that these are more money these players can make for the rest of their careers combined than just a single year. So for example in Kantes case, he could play 10 more years, and he would not make 100 million total, that's just not going to happen, and instead he is making more money in a single year than he could make anywhere else.
As I have stated before, Saudis could be rich but they are not rich enough to keep this going, for example if they did this for all 11, that would be 1.1 billion a year, we all know they won't do that, so they will pay less, and even at 50 million a year, that's 550 million a year, they won't even do that. Which means that they will get a few token players like these, and a few more smaller names instead of huge names, like iago aspas and so forth, and they will call it a day, won't make them top 10 let alone top 5.
There are many types of players, some really care about very tight competition in popular leagues so they stay at their current clubs, or they leave but are still in a competitive league environment. The players come here one of the factors is the fantastic money they will get, it will guarantee their future. I would not make a big deal out of this, because apart from being a hobby they are also working and have to earn money in their hobby. Arab clubs are one of the destinations where players can get high salary values, so they will be tempted, especially if they are entering retirement age.
