Am I missing anything about the uproar about this?
Mou played defensively at Anfield; United-fans applauded him, Pool-fans laughed.
Klopp played defensively at OT; Liverpool-fans applauded him, United-fans laughed.
To claim that either side is hypocritical without aknowledging the fact that they are so themselves is quite silly.
Long balls have a place in the game, spesifically when dealing with an immense pressure in the opposition half like Liverpool are very good at. There is one sure way to counter this pressure without risking the ball in dangerous positions, and that is aiming the ball at the massive man you have upfront. It's a way of dealing with a certain thread, just the same as playing it out from the back/applying high pressure/parking the bus/whatever.
I'm certain that neither side are satisfied with how the game turned out, as we both know that the teams can play much better than we both showed. Draw is a bit of a 'meh' result for either side, and it's silly for anyone to claim some sort of moral victory.
