The simple answer from my side to such questions is that everyone's personal favorite player is the best footballer in the world. It is probably known to everyone that everyone has a personal preference do everyone may have different opinions and bases, just like many people support Argentina so it is natural that they will choose Messi, just like many people support Portugal so they will choose Ronaldo. But personally, I think those who have played well in the past and are still playing well in the present and are well-known to everyone in the world today are all legendary players. We can never underestimate the players you mentioned here, we have to admit that they were or are very talented players at one time.
I agree with you, even for now, we have not seen players with extraordinary talents like them born again with achievements like them. We may hear some news associated with young talents who are reported as the successors of both of them, but to achieve the success that both of them have achieved, I believe it will not be easy for the current generation. But I believe that in every era there will be players who are at the peak of their career glory with the club they play for.
