I think it's too soon to speculate about Kevin De Bruyne's future and his potential to play for one of the Saudi Pro League teams, he still on the golden age and want to spent his career with top European teams exactly under Pep Guardiola he still become regular players with Manchester City. Indeed he has decision one day later will play with Cristiano Ronaldo but its less possibilities during Ronaldo have been 38 years old and Kevin possibilities moving to Saudi Pro League clubs exactly three or four years later.
Not really small with payment salary receiving from Manchester City, although Saudi Pro League teams will give more bigger payment I don't sure make excited for De Bruyne will play there and he needs right time before leaving top European teams.
I think a lot of people here say things they want to say because of engagement and how to fill the signature post. Why you even imagine that Kevin De Bruyne will leave for Saudi professional league. Not like his salary was small or he doesn't get comfort on how he play, he has won Champions League and Premier league title as well, if there is no better to do at Premier League, it's better for him to go to Seria A his Role model help rain, even Haaland wouldn't be desperate to make such kind of loves not to talk more of Kevin.
It's very sad that some players are hiding under the influences of Ronaldo but we all can agreed that he moved got good reason, Erik Ten Hag was pushing him to the walls and man was happy to leave but these players we are talking about doesn't look like they are been push by Guardiola(he doesn't have that time) and I don't think some of these players are cool going to a country to play for just because there is much money invest in players but soon all these candies will be dropped off.
