Arsenal striker Gabriel Jesus has lamented his side's failure to "kill" off the game against Manchester United as their perfect start to the new Premier League season came to an end at Old Trafford.
Mikel Arteta's side threatened the Red Devils backline and enjoyed the majority of the possession in the latter stages of the first half, but they were caught out by Antony's debut goal.
Arsenal did not let their heads drop and struck a deserved equaliser in the second half through Bukayo Saka, but two Marcus Rashford strikes condemned Arteta's side to defeat at the Theatre of Dreams.
Jesus himself threatened the United backline without managing to find the back of the net, and the Brazilian has admitted that his side were punished for not being clinical enough.
"The feeling is frustration, because we control the game and were better than them. And then we just concede. But now is the time to learn from it and improve," Jesus told the Evening Standard.
"We are doing so well this season, but there are still things to improve for everyone. Everyone is together and we stick together until the end, and that's it.
"We came to play against a strong opponent and it's always hard, it's the Premier League. So we are not happy, because we played so much better [than United].
"But that's football, if you don't go there and kill, you are going to have a big problem — and that's what happened today."
While admitting that Arsenal lacked a ruthless edge at Old Trafford, Jesus nevertheless reiterated that the Gunners have enjoyed a terrific start to the season with a youthful squad.
"If you look at our team, you can see we are still young. It is the youngest team in the League, in the toughest league of the world. We are playing so good and then we play against an opponent, who is young as well, but we have to learn from it," Jesus added.
"We have to, like I said, stick together and improve as a team and don't think about this one. This one is gone. We have to learn and then do better next time.
"We are playing so well, so good, but no one is perfect. No team in the world is perfect and we have to play to try to score and don't concede.
"That's football and we are doing this, but sometimes the opponent has quality as well. They come and they can score. I think now it is our challenge to improve a lot of things and come back strong."
With Manchester City only managing to take a point home from a 1-1 draw with Aston Villa, Arsenal remain at the top of the table after six matches - one point clear of the reigning champions.
Attention now turns to the Europa League for the Gunners, who are in action on Thursday night away to FC Zurich in Group A before resuming Premier League duties at the Emirates on Sunday against Everton.
On another sour note for the North London club, Emile Smith Rowe appeared to pick up an injury during the warm-down on Sunday, but the severity of the 22-year-old's problem has not yet been determined.
