Providing cautious rankings

I'm considering using cautious language when discussing transfer rankings since I can’t browse, and I definitely don't want to claim specific numbers unless I'm sure— that could be misleading! CIES provides a "Transfer Value Balance" metric and a "Cost/Performance Ratio" over five years, along with other calculations like estimated transfer values. They often release rankings on cost-effective recruitment for big European teams. For instance, the "Best buys of the last transfer window" and "Smart spenders" rankings give insight into ROI, where teams like Brighton and Brentford perform well, while United struggles.Analyzing transfer details
I'm examining the headline about performance over the last five years. It seems to imply a cutoff, which could exclude certain players like Maguire if we’re looking strictly at a 2020-2025 window. However, Maguire was signed in 2019, so he's on the edge. United still has players like Antony and Sancho whose performance may not meet expectations compared to their fees. Real Madrid leads, benefiting from signings like Bellingham and Camavinga, who produce high impact. PSG ranks fifth, attributed to key players but maybe with some mixed results.Summarizing CIES report

The user shared a headline, and they might be looking for a summary or more details. I think it’s best to start with a clarifying question, and also provide context about CIES. I can create a concise bullet list outlining how they measure cost-effectiveness through various metrics.
In general, CIES compares fees against sporting contributions like minutes played and performance. The findings include clubs at the top and bottom based on certain criteria. I can provide a concise Chinese explanation and ask if they want more information or a link!Clarifying transfer rankings
The user mentioned a global ranking, citing "皇马第一" (Real Madrid first) and "巴黎第五" (PSG fifth), along with possible other clubs like Benfica and RB Salzburg. I need to remind them about the time frame considered, typically the last five seasons or years, including rental players, and clarify that they usually focus on fixed amounts without fluctuating fees, while sometimes including add-ons.
If they want more details, I can provide the full list and key figures. Additionally, I can summarize Manchester United's transfer costs versus contributions over the last five years. I'll keep my response concise and in Chinese using bullet points.
