Manchester United boss Louis van Gaal has urged his players to behave like champions ahead of Saturday's away game against Everton.
The Red Devils suffered a heavy defeat against Arsenal before the international break as the Dutchman admits that it wasn't easy to analyse the game with key players leaving straight away for international duty.
"We are always evaluating ourselves and we cannot accept that," van Gaal told reporters.
"Not only the members of the staff, but also the players cannot accept that from each other because we want to be the champion - so you have to behave like a champion.
"You have to improve yourself so that in the future you can be the champion. You have to improve every time, which is what I am saying.
"I have analysed over the two weeks and that is awful when you have such a result!
"You cannot manage it with your players and that is what you have to do as a manager, but all your players are flying out [on international duty]. Especially the last game, because we played on Sunday, they flew out directly after the match.
"Then the players are coming back on Wednesday and also yesterday, like Romero and Valencia. They arrived after the training sessions so they could not participate in our meetings before the game against Everton.
"It is difficult for me as I still have to speak about the match against Arsenal because you have to analyse and learn from it and improve. I have to evaluate myself and how I prepared the players.
"I changed the sequence of preparation because I gave them Friday off, for example, and that is also an influence. Then I had to play 11 versus 11 [in training] one day before the game and give the analysis of Arsenal also one day before the game."
