Clarifying foreign player rules in CSL

I’m thinking about the Chinese Super League’s rules for foreign players. Historically, there was a limit of 4, but it seems like for 2023 and 2024, it has changed to allow 5 on the field and up to 7 in the matchday squad. There's a possibility that ACL Elite might allow more, but CSL has strict guidelines. The potential lineup for Shanghai Shenhua includes foreign players like Teixeira and Malele, though I'm not entirely certain about their status or history.Reviewing foreign player information

I'm analyzing the Shanghai Shenhua foreign players, and confirming that "马莱莱" plays for them. There's also "阿马杜," but I'm unsure about other names like "金敃友," who is a Korean defender. I think it's better to avoid specific names if I'm not confident. Instead, I can focus on a general analysis of the advantages and disadvantages of using 6 foreigners, including tactical shifts and match strategies. I’ll ask the user if they want a brief summary, context, or predicted lineup by providing numbered options.
