北青：国安德国总监1月8日上任，古加与恩加德乌确认离队（国安德籍总监将于1月8日履新，古加与恩加德乌已确认离队）

Proposing changes in CSL regulations

I'm thinking about the upcoming changes regarding the new German sporting director overseeing the winter window and a potential team rebuild. The departure of Ngadeu at center-back creates a gap, and Guga's exit impacts wing or back options. I need to clarify the registration rules for the CSL: currently, it's 5 foreign players allowed in a matchday and 6-7 in the squad. For 2024, the foreigner limit seems to allow clubs to register unlimited foreigners, and I want to confirm these details.Summarizing player changes

I see that we could translate the user's headline into English. According to Beijing Youth Daily, Beijing Guoan's new German sporting director is set to start on January 8, with Guga and Michael Ngadeu-Ngadjui confirmed to leave the team. I want to check if the user would like more context on these players, their contract statuses, or how this might affect the squad. I’ll keep my response concise, using a brief paragraph and 4 bullet points for implications.
