As for the fact that there is no need to push them further, there is no point in discussing this since the career of one player took place in laurels received thanks to officials, and the career of the second in conditions when he received laurels in spite of football officials. Nothing can be changed here. Even when they finish their careers they will be antagonists.
Playing in the club is not good as playing for the nation,because the nation play will help the player to set their own name.But if he play for the club,only the club name will define you,So you never get attached to the people.The fan for the club is low to the fan of the national player,So the most of the player play till their retirement age to the nation.This was the phenomenon of the player with average skills,the layer with more skill will lay for the club along with the nation playing.This is like Messi play for the Argentina and parallel to the other football clubs.The Mbappe itself play for the nation parallel to the other footall clubs along with their nation playing.
I don't know where you get these conclusions from. Playing for the national team is not only a job but also a privilege, which is why many football players (if they have great competition in the national team) leave the national team much earlier than club football. If you do not have the strength to compete at the top level and you are adequate to understand this, then you will leave the national team and change the club/championship to an easier one. This is the path most players take. By the way, there are questions for Ronaldo here
