Arsenal had 4-5 chances and deserved their goal, albeit from a penalty in the end. For an away team coming to Old Trafford, they will be very happy with this showing. As would we away to Arsenal at the Emirates, or Everton or any semi decent team really. Hit the bar from Willian, Lacazette «sitter» just before the touch from Lindelof in the box, Aubameyang’s shot outside the right post (their biggest), his sliding effort from Bellerin early on, Sako’s header totally unchallenged.. they were well worthy of a goal.
No they did not, half assed chances does not mean you deserve to win a game. They will be happy with the win, but the showing was average. Yes they hit the bar, so did we. Lacazette 'sitter', that never actually fell to him. Auba's shot which he missed, about worth as much as the chance by Greenwood that was stopped. Sliding effort that did not even reach him, and if Sako's missed header should deserve a goal, then Maguire effort should as well.
Again, does not matter how you dress it up, neither team deserved a goal, as neither team did enough to really get a goal apart from some half chances. That is not enough to say one team deserved to win over the other when both were very average. This was very similar to the Chelsea game, only no one made any moronic decisions in defending in the that game.
Hell, we could have had a pen as well, and Arsenal were fortunate to finish the game with 11 players. A close boring game overall, but nowhere near did we get battered to say that Arsenal deserved to win, but they did not deserve to lose either.
