Well and who will ever forget their win over Bayern in the 1999 CL Final when United turned around the game within 102 seconds just before the final whistle...! I remember Bayern fans all over Germany being completely devastated, hahaha.
I remember it well, if I was a Bayern fan I would have felt suicidal. Kind of like how I felt in Kiev when Karius decided to play like a 9 year old girl. I will never forget that night!
Just like I would never get over Barcelona loosing to Liverpool last season after a 3 - 0 first leg heroics, That was more humiliating than loosing a single final game to even Real Madrid despite being arch rivals.
