Group stage and knockout phase is two different things. Bayern Munich are still a strong team this season unlike Liverpool and Manchester United.
It was a bit similiar when we won the treble in the 09/10 season. Everyone expected Bayern to win the final but we got 2-0 quite comfortably.
It is what it is. Benfica were great in their group and seemed strong but after we defeated them they suddenly were not that great.
We are in the CL-final and deserve credit for it. Just because we made our opponents look weak doesn't mean they were weak.
In 09/10 no one believed in us and we knocked out all the becoming champions in Prime Barca, Chelsea and i think Bayern won that year while we basically owned them in the final. I think some english fans are bitter because of their loss to Italy in the Euros aswell.
Talk about history and stuff, Manchester United bring up their treble they won in overtime. We had a, without doubt, stronger treble than Manchester Uniteds so sure we can talk history.
It is what it is.
