Understanding Ajax's coaching changes

The user provided a Chinese headline about Ajax's head coach, John Heitinga, being dismissed after a poor performance in the Champions League. This seems to invite a more detailed response or context. I’ll want to summarize Ajax's recent coaching changes, noting that Heitinga took over as caretaker after Alfred Schreuder's sacking, only to later be replaced again. Also, they had a challenging season start in Europa. This context will help clarify the situation for the user!Clarifying the Ajax situation

The user mentioned Ajax's head coach Heitinga being dismissed, referring to a situation that seems off. Ajax hasn't recently participated in the Champions League; they were in the Europa League instead. So, claiming four losses in the Champions League doesn't add up. It’s possible this news is outdated or may refer to a rumor. Since my info is from before 2024, I should ask the user if they want a summary, confirmation, or sources for the news.Requesting clarification on Ajax news

The sandbox setup isn't clear, and while I'm usually unable to browse, I can ask for approval to access the network if needed. It's best to clarify what the user wants. They might be looking for verification of the news, background on Heitinga's tenure, or context about Ajax's season. I should quickly mention that Ajax’s claim of four losses in the Champions League doesn't match their recent schedule. I’ll present options in Chinese to keep it concise!
