Arsenal striker Gabriel Jesus felt they were the better side in Sunday's defeat to Manchester United.
The Gunners fought back to level at 1-1 and were on top until a late Marcus Rashford brace gave the hosts the win.
Gabriel Jesus said: “The feeling is frustration because we play, we control the game and the first two goals we concede we were better than them, the opponent.
“And then we just concede.
"But now is the time to learn from it and improve."
