With 10 matches left to play, second-placed Arsenal trail leaders Liverpool by a huge 15 points, albeit with a game in hand.
Arteta, who stomped away from a post-game television interview, rued the fact that Declan Rice’s second-half strike was their only goal against a struggling United side that are languishing in 14th place in the table.
“Very frustrating we haven’t won with the dominance and the chances we had in the first half. We gave the ball away out of nothing. Gave a foul away. We had them in the second half, you could feel they were really fatigued,” Arteta said.
“It was the threat in the final 25 metres to make something happen. They didn’t want to play. You come here and you want to win the game. Today, it is frustration.”
