Rodrygo, who is only 24 years old, should definitely not join a Saudi club right now. It would be a suicidal decision. Saudi clubs will pay a lot of money. However, there is not much discussion about the Saudi leagues. And very few people are aware of the Saudi Pro League. So if Rodrygo leaves Europe, he will be lost in a few days, we will forget about Rodrygo.
Rodrygo is very fast in attack and his fitness is good enough. I would say that Rodrygo should try to stay with a Premier League team. The Premier League is fiercely competitive and the squads are also strong. So if he is with a Premier League club, Rodrygo will be able to strengthen his performance day by day.
I am pretty sure he will play for a top European club, and for now, he can ignore the Saudi pro league clubs. There are rumors, Arsenal, Man City, and PSG are interested in him. If there are more people approaching him, I think Rodrygo will still get a place in a big club. With his age, even though the Saudi club will pay a lot, he will not go there. His career will still be good in a top European league.
