Manchester United boss Erik ten Hag admits their pressing has disappointed him this season.
Ten Hag made the complaint ahead of today's trip to Arsenal.
"That is one of the reasons why I was not pleased with it because the front and back didn't do their jobs. We got stretched and we have to improve that. We have to be more compact otherwise you can never counter-press," he said.
"I had the problem with how the defence moved and I had a problem with the responding in the defence transition of our offensive players."
Asked what the issue was, he added: "It is definitely attitude.
"[You improve attitude] by being demanding and matching standards. That is what I demand.
"Last year they showed they can do it in almost every game and I expect it even more. We can't make compromises because then you become vulnerable and you don't win games."
