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.
And now it seems that Chelsea is the club that has released the most players to the Arab League. There are already 4 Chelsea players who will join the Arab league such as Hakim Ziyech to Al Nassr, Edouard Mendy to Al-Ahli, Kalidou Koulibaly to join Al Hilal, and N'golo Kante who has already officially joined Al-ittihad. Even Lukaku, who was loaned to Inter Milan last season, has also received an offer recently from an Arab club. But Lukaku seems to have rejected the offer because he still hopes to play at Inter Milan. And Chelsea are also trying to sell Lukaku to Inter Milan. but Inter Milan seems only interested in extending the loan contract and is not interested in buying.
I think the Chelsea Club is really lucky because this club manages to sell players at a higher price than when the club buys. There are even several other names that Chelsea are also targeting to release to the Arab League.
