过往欧冠14次出现单赛季前6战全胜球队，最终仅2队夺冠（欧冠历史共14次有球队单季前6场全胜，但最终仅两队夺冠）

Analyzing Champions League performance

I'm reflecting on teams with perfect group stage records in the Champions League. Bayern 2021-22 and Ajax 2021-22 each had 6 wins but didn't win the tournament. Real Madrid also seems to have a complex history; they had perfect group stages too. Barcelona had a perfect record in 2002-03, but teams like Spartak Moscow in 1995-96 won all group matches and got knocked out. It looks like Real Madrid 2023-24 also had a perfect group stage and ended up winning.Counting perfect group stage teams

I'm trying to recall how many times teams have achieved perfect group stages in the Champions League. I think there are more than 14 instances. By 2021, there were at least 9, followed by Ajax and Bayern in 2021-22, bringing the total to 11. Then in 2022-23, Bayern did it again with six wins but got eliminated in the quarters. For 2023-24, both Real Madrid and Manchester City achieved perfect records too, although City got knocked out by Madrid. I also need to consider AC Milan in 1992-93; that was a different point system.Recapping perfect group stage winners

I’m thinking about how the early Champions League had two points for a win until 1995, when it switched to three. The number of wins remains a key statistic. So, let's list some known perfect group stage winners:

AC Milan in 1992-93, although I’m a bit shaky on their results since it was a two-group format. PSG in 1994-95 definitely won all six matches, reaching the semis but didn’t win. Spartak Moscow in 1995-96 had six wins before being knocked out in the quarterfinals. Barcelona in 2002-03 also had six wins but lost in the quarters to Juventus, and Real Madrid in 2011-12 did, too, but lost in the semis on penalties to Bayern.Summarizing Champions League performances

I’m reviewing several teams with perfect group stages. Real Madrid in 2014-15 had six wins but lost in the semis to Juventus. Bayern in 2019-20 achieved six wins and became champions, while Ajax in 2021-22 had six wins but fell in the round of 16. Liverpool also went perfectly in their group in 2021-22 but lost to Real Madrid in the final. I noticed Bayern in both 2021-22 and 2022-23 had six wins but got eliminated in the quarterfinals. In 2023-24, Madrid won again.Counting perfect group stage teams

It seems there could be 14 instances of perfect group stage performances following the 2023-24 season. Early on, teams like PSG in 1994-95 definitely had six wins. Spartak Moscow also achieved this in 1995-96, but didn't win the tournament. More recent teams include Liverpool in 2021-22, Ajax, and Bayern in various seasons, along with Real Madrid winning in 2023-24. My memory suggests no perfect entries before 1992-93. I can confirm two winning teams: Bayern in 2019-20 and Real Madrid in 2023-24, and provide a list of others that didn't win if needed!Clarifying Champions League performances

In reviewing perfect group stage teams, I found that Barcelona in 1993-94 and Milan had four wins and two draws, so they weren’t perfect. However, PSG in 1994-95 achieved a perfect record.

To clarify, the two champions from perfect group stages are Bayern in 2019-20 and Real Madrid in 2023-24. I can also mention some other examples like Liverpool and Ajax in 2021-22, Bayern in 2021-22 and 2022-23, as well as Manchester City in 2023-24.
