Even if Ronaldo gets Saudi citizenship, what would that mean for the football? Nothing. Even if he could, he still wouldn't be able to play for the Saudi national team because he played for Portugal. I really don't see the point in him getting their citizenship because as dar as I know, it's not forbidden for a foreigner to be a part of the group that will bid to host the 2030 World Cup.
As I mentioned before, Saudis don't want Ronaldo representing their national team. Their main aim is to host the FIFA World Cup of 2030. And they believe that Ronaldo can help them with this. And now for the question what would that mean for football - it would mean a lot. It is another proof for the rising fortunes of Asian and African teams.
It is not as low as Beckhams neither though, this one is for 75 million a year now matter what, and that is a ton of money, plus the extra that you are talking about. Basically what Beckham had was 30 million or so plus the incentives, and he got the incentives, and in this case we are talking about 75 million plus incentives, so if Ronaldo does get it like Beckham did, it will be 100+ million a year, not similar.
Obviously there are some calculations to be made regarding inflation, and maybe they are quite close to each other but I honestly believe that we are talking about a situation where it is much bigger payment for Ronaldo, doesn't look even similar to me.
Well.. I don't know whether Ronaldo or Beckham got a better package. What I know is that in both cases, the players received much higher salary when compared to their previous salary.
