Lol why can't United fans be proud, or why is that bullshit?
I get that for many people this is wonderful and they should enjoy it, that's the nature of football and the tribalism amongst fans.
Doesn't mean we as United fans can not be proud of our teams efforts or that is somehow a cop out. You ask for your team to at least give you maximum effort and our players did that. It's better than being knocked out by lying down or not showing courage which we have done in the past, for example when we lost to City 1-0 at the Etihad.
Anyway...
