Al Nassr didn't adopt FIFA FPP rule, so it's really impossible they will qualify to play in Champions League. Also personal invitation is a discrimination to other team especially Al Ittihad which previously won the Saudi Professional League.
With the absence of FIFA FPP regulations, Arab clubs are free to buy players at any price, including damaging market prices because other European clubs will be unable to compete in terms of offering prices to the players they want.
Clearly this is discrimination, if it is true that UEFA only invited Al Nassr, what about Al Hilal, who currently leads the standings? Maybe the Arab League champions will still choose Al Nassr? I don't think that's possible because there will definitely be many people protesting if this happens next season 24/25
It seems FIFA really want to bring traffic to their league since they falsely think, Ronaldo moving to Saudi Arabia is to end his career.
That's how according to several media, Ronaldo's move to the Arab League actually boosted his popularity, there were more and more fans, higher broadcasting rights, perhaps this is almost equivalent to broadcasting rights for other European leagues.
Maybe you thought at the beginning that Ronaldo's move to Arabia would end his career, but instead he became brilliant and is now the top scorer, compared to the MLS League, even though Messi has arrived, it is still dim in contrast to the Arab league.
