Realistically, i think the saudi arabia pro league is more suitable for him. because they can give him very high amounts of money in saudi arabia. also, since the competition is very high there, i think they will try to transfer such quality and good players. he has been competing with manchester city for years and achieving success. he is one of the best midfielders in the world. i think it is time for him to earn big amounts of money before he retires from football. the belgian player deserved it long ago. of course, he may have earned a lot of money during his time at manchester city, but the offer in saudi arabia will save him from financial difficulties for many years.
Kevin De Bruyne's current problem is his recurrent injuries. Manchester City had to bring in other players to replace him due to his inconsistency. But if the Belgian midfielder gets a permanent cure for his injuries, he might still have the strength to play in the top leagues in Europe.
The Saudi Professional League will be the best place for him to play. He can make more money and their games are not as intense as in Europe. The Gulf League can also tolerate his injury problems because they are not just focused on pitch performance. The SPL is bringing in famous players to give the League publicity and use their experience to groom young players. After all, Neymar earned so much in the league and didn't contribute much to Al Hilal.
