Keep in mind though that there have always been exceptions especially when it comes to the goalkeeper position. Buffon and other keepers have been around their forties or close to it and still participated in the big tournaments. I can see Neuer still being around in four years from now. Maybe he isn't first choice anymore by then, but he could still be a part of the team. That might also be the case for Muller, but it all comes down to their physical fitness and whether they are still playing by then anyway. But yes, this World Cup will be the last one for some of the GOATs. Hopefully we can enjoy some strong performances by Messi, Ronaldo and all the rest.
Here, we have nothing new because it's going into cycle many great players now in history books with their play and achievements so same going to happen with these legendary players as well because no one can stop time span and these players from coming older as we lost them surely we will have many new names even many are under development, but few are giving their best like Mbappé, Neymar and Haaland they could be new players to talk about and having something good for new generation kids.
Messi and Ronaldo were unique as we watch them for many years, and now it's time for them to give up and replaced with new ones, so we feel they are the greatest player in soccer history even we have too many names and performances from many legendary players in past as well.
Most chances Neuer are not going to stay here for next four years because he is not like we have Buffon or few others those give their best until age of 40 most chances he will be replaced soon with some better one.
