Jose Mourinho believes Manchester United have been found wanting for motivation in a difficult start to the season, but is expecting a big response from his side in Saturday's visit to West Ham.
United begin the weekend sitting seventh, eight points off the top of the Premier League, after defeats to Brighton and Tottenham and being held to a 1-1 draw at home by Wolves last Saturday after three straight wins.
That was followed on Tuesday by elimination from the League Cup on penalties at home by Championship side Derby County after a 2-2 draw at Old Trafford.
"I sometimes feel frustrated because with the work we do, I'm always expecting more," said Mourinho on Friday.
"It looks that when we feel we are really improving and playing better and having a good run of results there is always a little going down in terms of the focus or the motivation. I feel that."
"I expect to win tomorrow. I expect to play very well tomorrow. We worked very, very well - especially on Wednesday and Thursday, so tomorrow I expect a very good performance and I expect to win a very difficult match," said Mourinho
"I don't come here and say the training session was not very good, that the players are not committed and that I have a bad feeling."
