That's at best disingenuous and at worst a complete misrepresentation of why some people were so unhappy about yesterday. It's not about one game, it's about the last 18 months. It's about two squandered FA Cup Finals in which we were undone in the same fashion, it's about a 13 game run that read W1, D2, L10 and included three truly awful CL performances against Sporting, Feyenoord & Juventus and a shameful home defeat against possibly the worst United team we've ever faced, it's about the capitulations to PSG and Madrid and the thrashing at Arsenal, it's about conceding four goals (and it could have been eight) to a Saudi pro-league team in the CWC, and collectively it's about the complacency inherit in all of the above. No right back, slow centre halves pushed up on the halfway line and undone by the same long ball into the space behind them again and again and again and again, torturous backwards and sideways passing in the final third without ever attempting a cross or a shot, a lack of pace/legs in midfield, and to which we can now add persevering with that same modus operandii only with a goalkeeper clearing lacking the requisite confidence/ability required with his feet.
You're right, we don't have a divine right to win all the time and there's a section of our support who may have forgotten where we came from, but expressing one's irritation at witnessing the same flawed patterns over what is now a prolonged period of time, on a fan's forum, doesn't really constitute 'rag like' behaviour
