After Cristiano signed for Al Nassr he made the SPL look good for European football players. Many European players are in the SPL. Nunez and Felix will make the SPL famous than before because young fans will begin following their best players.
It must be admitted that Ronaldo's influence on the SPL has been significant. Before Ronaldo arrived, not many people watched the league, but after Ronaldo arrived, several countries even wanted to broadcast it on television. Likewise, quality players in Europe are increasingly willing to play in the SPL because the league is increasingly developing and competitive. In addition to players, top coaches are also starting to be interested in the SPL.
Ronaldo said that the Saudi Arabian League is indeed on par with the top five European leagues, but in terms of FIFA rankings, it is still far below them. I personally see the SPL improving. While they can't compete in European competitions, they can participate in the Club World Cup. I think this is one of the reasons why young players like Nuner and Joe Felix are accepting offers from SPL clubs.
