We usually aw some old players like Ronaldo join the Saudi League to end their career and they will choose to play for these Arabian teams because of the more money they can get in these teams while now it seems some young players are also interested in playing for these teams.
Ângelo Gabriel is a former player of Chelsea and he is a 19 player who plays as a winger and now he is going to play for Al Nassr in Saudi Arabia.

I think the reason why most Saudi Pro League clubs started with signing veteran players in the past was because these players were big names in football and were globally recognized so in their attempt to make the league popular among football fans across the globe, they were going for these veteran and popular footballers instead of signing young talents that will not attract global audience to the league. To an extent, they've been able to achieve their aim of attracting global attention to football in the Middle East country which is why they are now signing young talents.
Signing Ângelo Gabriel was a good transfer deal for Al Nassr even when I think they needed to sign quality defender instead of a winger. Hopefully for the Brazilian winger, he succeeds in his new club.
Ângelo Gabriel to Al Nassr is kinda a smart move. Its about creating for the future, not only about purchasing a headline. Thats how you create a league that lasts. This action might rewrite the story on the SPL. These days, they're not only retirement homes. Young players see opportunity, not a career dead end
Young stars are fantastic, but to grow them you need outstanding guidance. Without that, nothing is gained at all. Not to mention local talent either. Simply piling your squad with foreigners and hoping the league would flourish is not how it works. Though its a long trip, the SPL's on the right path. They must make investments in local players' development, coaching, and a competitive atmosphere. Only then will they be a force to be reckoned with.
