However, a player must have internal competition to be able to continue to develop his abilities, if he can very easily get a main place without any competition then that is not good in my opinion, the player will feel comfort and that comfort is what could kill their career, especially if The player is still young and still has a lot of time to continue improving his abilities so he can be even better.
Inside a club, there must be internal competition among players to get a spot in main squad. Without competition internally, star players will no longer have motivation to focus on training and improve themselves. It's very natural with everyone, not only football star players. Young players can compete with young players and can learn from senior star players, that will help young players to grow up faster and better. It's good for the club in general for quality improvement and maintain motivation of players.
At Paris Saint Germain he could get a very high salary, and not only that, he could also easily get a place. But I hope money is not a priority for him, he is still young he should think more about his career first because he still has a long way to go at the moment. If he is tempted just because of money, I'm afraid it will actually hinder his career development. It would be a shame if a player with excellent abilities and great potential were to simply disappear from the world of football.
High salary for players is like a double-edged tool that can sometimes force players to play better but sometimes will put them to parties and less focus on football from training to performance on field. There are examples over years that youth talented players self-destroyed their career because of money and party. Not all young players can cope well with money, life beyond football and lack of support from the club, parents, they will easily fall into many life traps.
Pressure at big clubs is another risk to destroy youth player's career. They're young and lack of experience to deal with big pressure and high expectation on them, so they're sensitive with attacks, critics from media when their performances aren't good enough.
