What teams have won the Champions League undefeated?

Question

With the Champions League finals coming this weekend, I was wondering if any team has ever won the Champions League or the European Cup without ever losing a game in both the Qualification rounds and Elimination rounds.

If it is a common occurrence, has any team ever won without conceding a goal, or accomplished that feat twice in a row?

Answer 1

Ten teams have won the European Cup/Champions League unbeaten, of which four have achieved this twice:

• Liverpool had 6 wins and 3 draws in 1980–81 and 7 wins and 2 draws in 1983–84.
• Milan had 5 wins and 4 draws in 1988–89 and 7 wins and 5 draws in 1993–94.
• Ajax had 7 wins and 2 draws in 1971–72 and 7 wins and 4 draws in 1994–95.
• Manchester United had 5 wins and 6 draws in 1998–99 and 9 wins and 4 draws in 2007–08.

The other clubs have achieved it on one occasion:

• Inter Milan had 7 wins and 2 draws in 1963–64.
• Nottingham Forest had 6 wins and 3 draws in 1978–79.
• Red Star Belgrade had 5 wins and 4 draws in 1990–91.
• Marseille had 7 wins and 4 draws in 1992–93.
• Barcelona had 9 wins and 4 draws in 2005–06.
• Bayern Munich had 11 wins and 0 draws in 2019–20.
