切尔西队史引进U20球员转会费排行榜：拉维亚6210万欧第一（切尔西队史U20引援转会费榜：拉维亚以6210万欧登顶）

Examining Chelsea Transfers

I need to respond to a Chinese user, likely looking for news or details about a statement regarding Chelsea's historical transfer fees for U20 players. The message mentions Lavia's transfer fee of 62.1 million euros, which probably includes add-ons. I'll compile a list of young players signed by Chelsea, like Andrey Santos, Carney Chukwuemeka, and others, noting their fees. It’s essential to provide accurate and up-to-date information from the cutoff in October 2024.Clarifying Player Rankings

I’m evaluating the ages and signing details of Chelsea players mentioned. Moises Caicedo, Cole Palmer, and Enzo Fernandez are above the U20 threshold, while Leslie Ugochukwu signed at 19 for around €27 million. Noni Madueke is technically 20, so he’s not U20 either. I’m considering that the user is referencing a specific ranking with Lavia at 62.1 million euros and might want the complete list. I think it would be best to clarify with a question: "Do you want the完整榜单?"Compiling Transfer Rankings

I’m looking to present a likely ranking of Chelsea's transfers, starting with players like Lavia and Gusto, along with their transfer fees. There are several names around the €15 million mark and below. I notice these details are older, though, so since the user might be referencing an article, I should ask if they want the full list and how they define U20. I’ll reply in Chinese with a succinct question: 需要完整榜单、统计口径、数据源? This keeps it concise and to the point!
