Clarifying player valuation change

It seems like the user is looking for an explanation regarding Transfermarkt's valuation change for Conor Gallagher. But I’m wondering if there's confusion since Gallagher plays for Chelsea, not Atlético Madrid. I also thought about other players with the surname Gallagher but couldn’t find any at Atlético. It looks like the name "Gallagher" typically refers to Conor Gallagher in this context. Overall, I’ll focus on providing information about his situation at Chelsea.Explaining Transfermarkt's reasoning

I see "马竞" refers to Atlético Madrid while Conor Gallagher is linked to Chelsea. I wonder if the user is asking about a hypothetical transfer or rumor? I thought about other players but couldn’t pin down a Gallagher at Atlético. It seems like I should provide a concise explanation of Transfermarkt’s valuation process, focusing on factors like playing time, performance, and role. I should also mention Gallagher’s limited minutes at Atlético might impact his valuation. Should I ask if they want a news brief or a social media post?Formulating the response

I should keep my analysis general and avoid specifying exact amounts. I’ll create a brief analysis with bullet points on reasons for Gallagher's devaluation and what could help recover his value. I want to offer a concise news lead rewrite and options for a headline.

I’ll summarize the core logic of Transfermarkt's valuation factors, detail his role at Atlético, and outline how he can improve his situation.

Also, I should clarify which Gallagher the user means, just to be sure!
