Young players can also become fatigued if the formation and tactics they employ are not appropriate, and they need to be mindful of this before the season actually gets underway. Throughout the season, every team will strive to consistently win matches to avoid being overtaken by their opponents. Soon, everyone will also be watching Chelsea's performance in the Club World Cup. This is also an important opportunity to assess a team's performance before returning to their respective domestic leagues.
Young players are more vulnerable to the difficulty of controlling emotional and not wise in making decisions. Another weakness of young players in a mentality will not be as good as old players.
But there are other advantages when Chelsea do a big overhaul filled with young players in the long run will get a stable performance. This is the reason Chelsea build a club with young players.
In the upcoming match I doubt Chelsea can withstand PSG attacks. Maybe more workers are conceded with a large score.
