I gotta say, Utd-Liverpool sure didn't feel like the biggest game in football this time around.
Maybe it's due to corona, but it was hardly mentioned in the press here. It didn't help that it was a fairly boring draw off course.
I think El Clasico still is the biggest game. There just always seems to be so much on the line. The title (usually), the Messi-Ronaldo rivalry (or now: the Messi unhappiness), the whole political mess, often one of the coaches job hanging by a thread, etc.
When was the last time Utd-Liverpool was played with the title on the line?
