United face Leicester City tomorrow after losing their past two Premier League games.
Mourinho said today: "We are a team…we all started well. We all won four matches and we all lost three matches in a week and that's not Wayne Rooney.
"Everybody is involved in every match.
"We lost three matches when we were not consistent. We played well for periods and not the whole period of the game. In football you have to be consistent for the whole 90 minutes."
