The Chinese Super League (CSL) is set to add four new clubs this season, bringing the total number of teams to seven in the league. The move comes after the league announced it would expand its entry pool by adding three more teams to the 2021-2022 season.

The CSL has been struggling in recent years, with several clubs having struggled financially and attracting little interest from fans. However, the league is now looking at ways to improve its financial standing and attract more clubs to join the league.

In addition to the four new teams, the league will also be expanding its entry pool by adding three more clubs. This move comes as the league looks to increase its participation in domestic football and improve its competitiveness.

The expansion of the league's entry pool is seen as a positive step towards increasing the league's overall popularity and appeal among fans. It will also give the league greater control over its finances and allow it to focus on attracting top-quality clubs and players.

Overall, the addition of the four new teams to the league is a positive development that should help the league continue to grow and thrive in the coming seasons.
