Kelvin de Bruyne is an important player in the Manchester City squad, so Manchester City will not just let him leave the squad, especially since he is now in his best form. We can see that when Manchester City had to play without the presence of Kevin de Bruyne, they experienced a little problem when attacking because usually Kevin de Bruyne was the mastermind of Manchester City's attacks. He is creative in sending passes so that his teammates can use them to score goals.
Pep Guardiola also definitely wants to see him in the squad because he is one of the mainstay players for this coach. Even if he leaves, then I don't think the SPL is his goal, I think he will choose a big and competitive league. He will still stay at Manchester City and help Manchester City to achieve further success. He has become a key player for Manchester City's game, so there is no reason for Manchester City to sell him to another club. Kevin de Bruyne's contribution is still very much needed.
Being 32 years old does not make Kevin De Bruyne lose his performance and also his role at Manchester City, at this time De Bruyne is no longer as fast as he used to run but like other great players De Bruyne now relies more on his experience and technique in playing smart to overcome his physical fatigue, and that is what makes De Bruyne still gain the trust of Guardiola in the Manchester City main squad, But I think now his injuries will make him slowly fall out of Guardiola's options.
Football is not far from being a business, so when you say he will stay two more seasons at Manchester City of course I disagree, because after all business De Bruyne will be able to generate a big income for Manchester City if they sell him next season while he can still maintain his playing form, so far reportedly Manchester City are starting to look for successors to replace De Bruyne and Alex Baena from Villareal and Florian Wirtz from Leverkusen is reportedly a target for Guardiola next season to be recruited, besides the small chance of De Bruyne staying at Manchester City next season because currently they have pegged 100 million euros for the Saudi Arabian team who want to sign him, so far reportedly Manchester City have received bid proposals from Al Nassr, Al Ahli, Al Ittihad and Al Hilal to sign De Bruyne next season, So of course Manchester City will benefit greatly right now than Release him on a free transfer in the summer of 2025.
