The second round of the China League Soccer (CLS) season is underway, and the two teams that have impressed so far are Shanghai Shenhua and Shenzhen Dalian RSCA. Both teams are led by experienced coaches who have been in charge for years and have built strong foundations.

Shanghai Shenhua has had a successful season, with a number of key players returning from injury and making their debut this season. The team's defensive solidity and ability to score goals have been praised, and they have shown great promise as a team.

On the other hand, Shenzhen Dalian RSCA has also made significant progress in recent seasons, but their performances have not been consistent. Despite having a few talented young players, their defense has struggled to keep opponents at bay, and their goal-scoring abilities have not been impressive enough to justify their high expectations.

In terms of performance, both teams have shown some promising signs so far. Shanghai Shenhua has a good combination of talent and experience, while Shenzhen Dalian RSCA has a strong foundation but may struggle to compete with the likes of top teams like Shanghai Shenhua and Guangzhou Evergrande.

However, it remains to be seen how these teams will perform against each other in the second round. With a lot of time left until the end of the season, both teams will need to focus on building their strengths and improving their weaknesses if they want to secure a spot in the playoffs.
