This time I agree with your opinion after Ronaldo played in the Saudi Arabian League. Hundreds of thousands of football fans switched to the Arab League. Every Al Nassr match is always crowded with spectators, much different from teams in other Arab leagues.
With the presence of several European star players in Arabia, it will make the League Arab countries are increasingly progressing even though Cristiano Ronaldo no longer plays in the league.
Well.. Europeans find it difficult to admit that their supremacy in football is over. There was a time, when the European leagues such as Emglish Premier League, La Liga, Bundesliga, Serie A, Ligue 1 and Eredivisie used to have complete monopoly as far as association football is considered. All the top players used to prefer one of these leagues. But now times have changed, with players mostly preferring Major League Soccer and Saudi Professional League. Even J1 League and Chinese Super League are now becoming popular across the globe.
From the spectator's point of view, I still think the English premier league and other European leagues are more popular. The Arab leagues and Chinese leagues are emerging but they cannot take the place of the ones already running for ages. Yes, the players want to play for Arab Leagues as they offer attractive packages but still i will not believe that Asia have become supremacy in football as yet. They may never become as there are very few Asian countries that play quality football.
