The CSL Round 23 match preview between Shanghai and Chengdu is set to take place on September 17th at the Guangzhou Sports Center. The game will kick off with a live broadcast on the CSL TV website, while the video stream will be available through the CSL app.

Shanghai has been performing well in recent seasons, having won the Premier League Cup twice this year. They have also secured two domestic cups, including the Chinese Super League and the Chinese Cup. However, they haven't been able to dominate against more established teams like Chengdu.

On the other hand, Chengdu has struggled recently, but they have managed to secure some victories in recent matches. Their most notable victory came against Shanghai last season, where they defeated Shanghai 5-0. They also won the Asian Club Championship in their previous campaign.

In terms of team performance, both sides have shown signs of improvement over the past few months. Shanghai's players have been working hard to improve their fitness and technique, while Chengdu has made improvements in their defensive strategy. However, the key difference lies in their overall quality and experience.

Overall, it seems that both sides have the potential to perform well in this match. It will be interesting to see which side can emerge victorious and advance to the next round.
