The biggest and best clubs in Europe have all enjoyed lengthy unbeaten runs in the Champions League.
The Champions League pits the best teams from Europe's top leagues against one another in an action-packed tournament. The competition is the only time in a domestic season where clubs from the Premier League, Bundesliga, La Liga and more can face off for one of the most coveted trophies in soccer.
Conquering the Champions League is one of the most difficult feats in club soccer. Some of the most successful and historic teams across Europe, including Paris Saint-Germain and Arsenal, have never topped the UCL.
Only eight teams have gone on historic undefeated streaks in the European competition. Recent dominance from Manchester City and Bayern Munich saw both sides go years without a single defeat in the UCL.
Here's the 12 longest unbeaten streaks in Champions League and European Cup history.
