Manchester United boss Louis van Gaal blames a below-par performance from his side for their first FA Cup defeat against Arsenal.
The defeat means United will end their first season under van Gaal with no trophies but the Dutchman insists the main objective is to finish in the top four and secure a Champions League spot for next season.
"I've said in the dressing room we gave [the game] away by ourselves and that is the biggest disappointment," van Gaal said.
"In the second half, we had the first chance also then we gave it away again.
"We didn't lose [because of] the opponent, we lost from ourselves and it was very disappointing.
"You play this match to win; to beat the opponent, we wanted to be in the semi-final.
"I said in advance that [the top four] is a priority but as a manager, and as a player and club you want to win titles and now we cannot win a title."
Asked about Angel di Maria's red card, the Dutchman said: "In Spain he knows that he doesn't touch the referee, but that is also in his emotion.
"I've already spoken with him, he knows my opinion but also I have to see on the video.
"I think he's touched the referee and that's forbidden in every country, so he has no excuses."
