Erik ten Hag wants his Manchester United players to "suffer" in order to achieve success this season.
The Red Devils bounced back from two shocking defeats to overcome Liverpool at Old Trafford on Monday night.
Speaking after the game, ten Hag said: "What I demand is that players bring the top spirit every day. Every day, they have to bring it to the club.
"It has to be a way of life and I hope they understand. It's only working - high performance, high level - if you have that spirit and have that focus.
"If you accept that you have to hurt yourself, you have to suffer, to finally get the best level out of you."
