Manchester United boss Erik ten Hag says they must learn from their defeat at Arsenal.
United, after a midweek draw at Crystal Palace, lost 3-2 at Arsenal on Sunday.
Ten Hag said: "I think [the] two games head-to-head [versus Arsenal and Crystal Palace], they were really close. It is hard to accept that in the final stages of the game you lose and this can't happen. We have to face that, we have to learn lessons, and that we are going to make mistakes as I think all three goals were avoidable. Normally we are better in those situations.
''We are good in certain situations but it is tough, as we have had a lot of games that they didn't have. Then in the end they come and play at home and you can smell it. I think there were moments we were brave. In the end we have to be much better in those situations, we make the wrong decisions and this is not just one player, but many more players.
"Then you concede a goal which as I said we must avoid, this is the same for the first two goals. We started the game very well, we scored the goal and we are leading but we are making mistakes which are unacceptable. Today we must learn the lessons and move on.''
Ten Hag also said on the title race, ''We never talked about it. That is from the people around us and the fans and [we just] want to win every game. We showed that today, as we were brave, but then you see we created chances. As I said, if you want to win trophies, you cannot make those mistakes like we did tonight.''
