Considering news commentary

I need to respond to the user discussing a news headline in Chinese about football transfer values from CIES. The user posted a statement about Manchester United's performance compared to other teams, which likely needs some clarification or a brief summary. I can explain who CIES is, what metrics they use, and provide context. But, oh no, I must be cautious about potentially outdated info, since my knowledge goes only up to October 2024, and I need to confirm my data permissions first.Providing context and details

I need to avoid making specific claims if I'm uncertain. It’s better to ask the user if they want more details or a source link. I can explain the CIES transfer value-for-money index, which compares team performance against transfer fees and wages. Manchester United's underperformance is notable compared to Real Madrid's good recruitment—players like Vinicius and Bellingham provide high value. PSG being fifth likely relates to mixed spending. I can ask if the user prefers a summary of key rankings or reasoning.Clarifying transfer metrics

I noticed Mbappe joined PSG for free in the 2024-25 season, which influences their fifth-place ranking; they've improved but still have high spending. I need to provide caveats about the model and its time window. I can ask if the user wants the full ranking or raw numbers. It’s important not to fabricate specifics, so I could say something like "the report says..." and offer to fetch it if they need it. I’ll explain "引援性价比" as a transfer efficiency metric, comparing transfer fees and wages to minutes played and overall impact for the last five seasons.Explaining CIES methodology

The CIES methodology involves publishing "transfer value efficiency ratings," comparing estimated "fair transfer value" to paid prices and on-field performance. They also use an "Impact Score" which looks at the performance-to-cost ratio. To stay accurate, I’ll keep this generic by focusing on cost versus contribution.

Here are some bullet points:

• Manchester United ranks last due to high transfer fees, wages, and inconsistent contributions from players like Antony and Sancho.
• Real Madrid tops the list with low net spend and high success rates, featuring players like Bellingham and Vinicius.
• PSG is fifth, benefiting from youth development but faced heavy spending early on.

I'll mention that the model uses a five-year window, which may dilute recent improvements, and I'll ask what the user prefers—full rankings, specific scores, or a visual summary. I’ll propose summarizing the original CIES report as well.
