Clarifying coaching options

I want to clarify the user's question and provide concise takeaways. If true, it seems Poyet left his position to support his assistant, and CSL's interest indicates a return to China. He previously managed Shanghai Shenhua in 2017 using a 4-2-3-1 style. I should consider the pros and cons for CSL teams. I can propose options to the user: a quick summary, identifying CSL clubs with vacancies, tracking confirmations, or comparing Poyet's fit with top CSL teams. Let's keep it concise!
