#1 Barcelona 6-5 Paris-Saint Germain (2016-17)

Even before you started to read this article, you would have probably guessed the first. This round of 16 tie is the most recent one and I don't think there has been any better in the Champions League.
The first leg was played in Paris and Barcelona came into this tie as sure-shot favorites. But PSG had other ideas as they just destroyed the Blaugrana in this match.
PSG scored 4 goals in the first leg, thanks to a brace from Angel Di Maria and goals from Julian Draxler and Edinson Cavani. The tie looked just about settled then, but more drama was to come.
In the second leg, the task was clear for Barcelona - score 4 goals and at least take the match into extra time. The Blaugrana started the match on fire as they blazed away to a 3-goal advantage thanks to goals from Luis Suarez, Andres Iniesta and Lionel Messi.
The 62nd strike by Edinson Cavani seemed to have settled the tie, but then something astonishing happened. Barcelona scored 3 quickfire goals in the space of the last 10 minutes to complete one of the greatest comebacks in the history of football.
Those scenes of joy at the Camp Nou were a sight to see.
