Arsenal manager Mikel Arteta bemoaned the decision not to award his side a penalty for a high boot challenge from Kyle Walker.
The Gunners showed steel and spirit throughout, but failed to find the cutting edge as they fell to a 1-0 defeat versus Man City.
Raheem Sterling notched the game’s only goal in the first-half, but Arsenal did remain in the contest until the final whistle.
Speaking to Sky Sports following the match, Arteta said: “I am upset, because I think we deserved more from the game.
“I am extremely happy about the performance we put in today, against a top, top team.
“To come here and play with the attitude, and to have the courage to play the way we played today, to make it as difficult as we made it, I have to say I cannot demand much more from the players.
“Apart from to say that when you have three big chances, in this game you have to score.”
When asked which was the best opportunity, Arteta pointed to the non-awarding of the penalty following Kyle Walker’s high boot challenge while attempting to clear a corner.
“I think the three of them were really good, and obviously the situation we have with the corner and Kyle Walker.
“That has to be checked [by VAR]. They said that they checked, and I asked ‘How the hell have you checked if you took two seconds to check that action?!’
“Obviously there is something there.”
