The new U23 player appearance rules have been implemented by Chinese Football Association (CFA) and the league is now open to all players under 23 years old.
Under this rule, all players under 23 must wear white shirts during matches in the CSL, while they will not be allowed to wear any other color or pattern on their jerseys.
This change has been made to ensure that the players are aware of the rules and adhere to them at all times.
Players who break the rules can face disciplinary action such as fines, suspensions or even expulsion from the league.
It's important to note that the new rules only apply to the CSL season, so players who want to play for other leagues may need to adjust their appearance accordingly.
Overall, this move is a positive step towards improving the quality of football in China and ensuring fair play in the sport.
In conclusion, it's essential for all players under 23 to follow the new U23 player appearance rules in order to maintain the high standards of the game.
