Considering user statement in Chinese

The user's message translates to a statement about Liverpool defeating Real Madrid four times with clean sheets in the Champions League, which is interesting! They haven't asked a specific question, so they might be looking for clarification or additional context. I can acknowledge the information and provide relevant match history or head-to-head statistics. However, I need to ensure that I’m accurate about sports facts, especially since my knowledge only goes up to October 2024.Reviewing Liverpool vs. Real Madrid matches

I need to clarify Liverpool's clean-sheet victories over Real Madrid. In the 1981 final, Liverpool won 1-0, which is a clean sheet. Then, in the 2008-09 season, they had two matches with clean sheets: 1-0 away and 4-0 at home. That totals three clean-sheet wins. In contrast, Real Madrid won several matches against Liverpool without any clean sheets for them. So, Liverpool’s clean-sheet victories are limited to those few instances.Clarifying Liverpool's clean-sheet wins

From what I'm piecing together, Liverpool has three clean-sheet wins against Real Madrid: the 1981 final with a score of 1-0, and two victories in the 2008-09 season with clean sheets, 1-0 and 4-0. There hasn’t been a clean-sheet win in other encounters. I thought about other matches in different years, but it seems those don’t qualify for this count. So, it looks like the total stands at three, not four.Examining Liverpool's clean-sheet record against Real Madrid

The Chinese headline states that Liverpool has four clean-sheet victories over Real Madrid, which might count all European competitions, not just in the Champions League era. I can identify three clean-sheet wins: the 1981 final (1-0) and both legs in the 2008-09 season. There hasn't been a fourth confirmed match, and while some historical records might include older competitions, I'm not sure where that extra win would come from. It’s puzzling!Clarifying Liverpool vs. Real Madrid stats

It seems the user might be referencing Liverpool's clean-sheet victories over Real Madrid, but there’s some confusion. I’ve identified three clean-sheet wins: the 1981 final and two wins in the 2008-09 season. The user’s claim of four might be including a draw. I should ask if they’d like me to fact-check this information or provide context. It could be helpful to check specific seasons or clarify what they mean by "零封" (clean sheet) and "击败" (victory).
