This week showed us that anything is possible in football. Tottenham and Liverpool's astonishing second leg performances obviously prop up our list, but which other matches made the cut?
Anything can and usually does happen in the beautiful game!
Roma 3-0 Barcelona
Barca had beaten Roma comprehensively 4-1 in the first leg in Spain, but a late goal from Eden Dzeko ended up being crucial for the Italian side. Kostas Manolas headed home the winner from a corner kick 82 minutes into the second leg capital clash and caused pandemonium in the stadium. This would prove to happen to Barcelona again against Liverpool in even more dramatic fashion at Anfield the next year.
Barcelona 6-1 PSG
2016/2017 round of 16
Lionel Messi, Neymar and company pulled off the biggest comeback in Champions League history after wiping out a 4-0 first leg deficit, only for versatile academy boy Sergi Roberto to hit an injury-time winner and stun the superstars of PSG into silence.
PSG haven't recovered from that disappointment to this day it seems, even with Neymar in their ranks, as they fell apart on another incredible night of comebacks when Manchester United vanquished them this season in the round of 16 stage.
Ajax 2-3 Tottenham
Lucas Moura scored a hat-trick that he, his supporters and pretty much rest of the world will remember forever in Tottenham's dramatic stoppage-time win over a heroic Ajax side.
In the 96th minute of the match, Ajax was poised to advance with a 2-2 scoreline but Brazilian Moura popped up to break Dutch hearts and eliminate the young, talented and increasingly popular Ajax side. Moura was in tears after the match when he was showed commentary of the winning moment by some fellow Brazilian telecasters.
Ajax had their chances but this will be a painful memory that might leave scars for a while.

Liverpool 4-0 Barcelona
Most sides wouldn't be confident of turning around a 3-0 deficit against a Barcelona side with Lionel Messi in it, but this is Anfield and this is Liverpool.
Mo Salah and Roberto Firmino were both ruled out of the match with injury and that lengthened Liverpool's chances even further. Divock Origi, one of the beneficiaries of these injuries, scored a crazy, tie-clinching goal thanks to a clever pass from Trent Alexander-Arnold off a corner.
The scenes after the match involving tearful Liverpool players singing "You'll Never Walk Alone" arm in arm will live long in the memory of fans the world over.
Liverpool 3-3 AC Milan
2005 Final (Liverpool won on penalties)
The Steven Gerrard final. Milan seemed to have the game sewn up, leading 3-0 at half time and infamously singing in the changeroom at the break. How foolish that proved to be. Stevie G rose highest to pull one back, Vladimir Smicer scored from range and then Xabi Alonso scored from the spot to take the match into extra time.
Andriy Shevchenko hit his penalty tamely at Jerzy Dudek and Liverpool had pulled off a miracle in Istanbul.
Will Valencia turn things around against Arsenal tonight in the Europa League. Let's wait and see.
