The Chinese Super League (CSL) is the top-tier professional football league in China, and it has had a significant impact on the performance of various clubs throughout its history. One such club that has seen its statistics improved by the CSL is Beijing Guoan.

Beijing Guoan is one of the most successful teams in the CSL, having won the league title eight times since its inception in 2011. However, before joining the CSL, the team struggled to find success on the domestic stage. The team was relegated from the CSL in 2017 after finishing last in the regular season.

Since joining the CSL, Beijing Guoan has experienced a transformation. The team has been able to improve its defense and midfield, which has allowed them to win more games and secure better results. The team has also made improvements to their attack, with new signings like Wu Lei and Ye Shi improving the team's attacking prowess.

One of the key factors behind Beijing Guoan's success in the CSL has been the addition of players who have experience playing in Europe. Players like Wu Lei and Ye Shi, for example, have played in top European leagues and bring a wealth of knowledge and experience to the team.

Overall, the CSL has had a positive impact on Beijing Guoan's statistics, allowing the team to compete at the highest level of football in China and achieve greater success than they were able to achieve previously. With continued investment in the team and the support of the CSL, Beijing Guoan will likely continue to be a force to be reckoned with in the league for years to come.
