Kevin De Bruyne had one time said he'd love to play with Cristiano Ronaldo before he retires so I do feel like his next destination would be Al Nassr definitely.
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.
In the near future Kevin De Bruyne transfer looks unreasonable, Manchester City has strong finances to pay the player desired salary. Pep Guardiola will also keep Kevin De Bruyne at Etihad, currently it is very difficult to find a player of the caliber of the Manchester City captain, he is the most valuable asset along with Erling Halaand at the moment. All players are definitely interested in experiencing the same team as Ronaldo, it is an honor to be able to play with one of the best stars.
Kevin De Bruyne contract at Manchester City ends on June 30 2025, which I think he will stay at the Etihad until his contract expires. The core of Manchester City attack comes from his feet, we can see some time ago when the player suffered an injury, Manchester City immediately experienced a difficult period to win and suffered several surprising defeats. So it is very natural that club officials will try to retain Kevin De Bruyne.
