Here re we go again, the blind football fan. What on this earth makes you so confident that Arsenal will finish above Liverpool and United? Have they really improved the squad that much so far? Also your lack of knowledge is fantastic, Liverpool did not have a full strength team out and it was a pre season marketing tool.
I think you are trying to be a WUM going on the fact that you keep changing your opinion and avoids questions when asked.
I don't think your squad was that weak, and isn't that part of the game. Have a squad good enough to cope. UTD were also in ore season and as you've stated earlier have a squad with holes. Yes it was a friendly, but whichever team won was going to brag somewhat whilst the others hid behind it being a friendly. Didn't they say at the start you've now had 2 friendlies in your history? Says it all really, the fans at the game whilst mainly yanks still wanted their respective teams to win.
