I understand why fans dislike the club at times, it isn't so much that. More making joke about Juan
As for your points
1) That is the way we play though, we always look for another goal. Against Chelsea last year, that same approach to going for goal rather then corner flag saw Cech make saves, Cashley clear off the line and us have two goals ruled out. That day it worked, last night it didn't because Almunia can't save long shots. We tend to try and play our way out of trouble, heck Hleb used to dribble inside our six yard box, not out of arrogance but we boot it and it comes back out us. We play it too feet and we can break. Course this leads to times when it comes back to haunt us but other days, it works.
Who showed desire? Almunia to single-handedly destroy us. Gallas, Silvestere, Clichy who kept going after the error, Cesc, Walcott, Nasri, Denilson, Diaby (too eager), Van Persie, Ade. They worked hard, it wasn't arrogance that cost us but poor keeping. Man U stuffing in Fa Cup, that game we didn't try with the exception of Gallas, Nic and Jens, this one we did.
2) He sometimes has fair complaints and he rarely criticizes his players as a policy but he does go too far sometimes, he should give more credit to the opposition.
3) You do see the criticism the press gives us? Yes they drool at our football but they slam into Gallas any chance they get (mind you the fans do that to him and Ade), they keep predicting 5th, come up with the old clichés about not liking it up em and encourage players to hack. When Arsene complained about a punch to Van Persie's stomach by Morgan, they lambasted Arsene and our wussy players for complaining about it, when Pederson tried to stamp on Cesc's neck, they called it fair. The old "Arsene hates the English" criticism has died down though since Walcott.
4) He has been cutting that out.
