Mikel Arteta was understandably frustrated after we were beaten 3-2 by Manchester United on Thursday.
Training 2-1 in the second half, we fought back to equalise and were getting on top - only to give away a penalty.
"First of all to show the character and the personality and the courage to play the way we did at Old Trafford [was pleasing]," Arteta told Arsenal Media.
"But, the reality is, conceding three goals at Old Trafford, it’s very difficult to get any result and when the game was there with 2-2, and we were in our best moment and had total control and dominance of the game, that’s when you have to give the next step and go and win the match and then we didn’t manage one situation, we open up and we concede the penalty and we throw the game away.
"We are here to win football matches and I’m disappointed because I have the feeling that we deserved more.
"But again, we have to be realistic that if we do what we did in certain moments, defend in our box against probably one of the best squads in the world, they’re going to punish you because they have so many goals and quality to define those moments and that’s the curve and hopefully the lesson that we have to take from today."
