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.
But in this case we must also be aware that with what KDB is showing now then leaving early to the SPL with his current performance which is still very feasible in the big leagues in Europe it will be a wrong decision for KDB because after all for now we must be aware that currently KDB is still a good attacking motor for Manchester City and if you really want to leave I think there must be a better club than for the SPL.
Its not wrong to want to go to the SPL because there will definitely be big money that he will get in terms of salary but we can be sure that it will also make his popularity different.The SPL is indeed a good destination for athletes now where money can flow easily but for a player whose career is quite good like KDB at the moment then moving to the SPL in a hurry I think it is an inappropriate decision.
