Manchester United boss Erik ten Hag says their defending must improve after defeat at Arsenal.
United lost for the first time in 11 games at the Emirates as Eddie Nketiah's 90th-minute strike sealed a 3-2 win for the Gunners, with Ten Hag claiming that all three goals were 'avoidable'.
As United look to get back to winning ways in the first leg of the Carabao Cup semi-final at Nottingham Forest on Wednesday night, Ten Hag urged his players to learn from their mistakes.
"In general, against Arsenal we defended very well," said the Dutchman. "They didn't get clean shots, was one time from free kick. There was a lot of defence between the ball and the goal.
"But all the goals were avoidable and that's my point it cannot happen. When you concede three goals in a top game you can't win, that's one of the conclusions. We have to take this lesson.
"We left it behind. We said the right conclusions, then we have to move forward and quickly because tomorrow is a big game and focus on that."
