That's because the team from Saudi Arabia was able to provide a bigger salary than they received in their previous team. I think one more thing is that they want to make the Saudi Arabian league more widely known by bringing in many well-known players from the EPL. From last winter's transfer window, teams from the Saudi Arabian league were very aggressive in making approaches with star players from the European league, so it wouldn't be surprising for us if they would do even more in this season transfer window.
And also this is a big advantage for the EPL team where they sell their players at high price to the Saudi Arabian league team. But some of them certainly still want to stay in the European league and will refuse offers coming from the Saudi Arabian league team.
Yes, this time the Arab League is incessantly bringing in world-star players, Ronaldo's arrival at Al Nassr is the opening door for other star players to have a career in Arabia. As many as ten players are reported to have been on the radar of the Arab League hunt and the average of them is over 30 years old which can indeed be said to be approaching retirement age. It cannot be denied that in this hunt, in my opinion, all parties benefit from each other, I do not think that the players can refuse the fantastic offer offered by the Arabs and their arrival will indirectly have a positive impact on the Arab clubs who have brought it. In terms of the club's prestige, it is clear that it will increase significantly and apart from that it will also be able to bring in more spectators, especially fans of these star players. I don't see the disadvantaged here.
