Mourinho calls for consistency from Red DevilsSports | Apr 17, 2018
Mourinho immediately faced the question of whether he was confident his team could make a real challenge in the Premier League next year.
"I trust in my work, that is for sure. I have no reason not to trust," the United manager said. "Eight titles are eight titles and three Premier Leagues are three Premier Leagues.
"The last title was not 20 years ago, it was three years ago. I know how to win, I believe in myself but I don't play," the former Chelsea and Real Madrid boss added.
"In my experience you don't win titles with inconsistency. You win titles with quality. Without quality you have no chance, but you have to win titles with consistency at every level, not just the performance level.
"The mental level, the day by day, everything must be consistent until the last day so one of the things we have to improve is consistency."
Mourinho suggested his players might have over-reacted to the win against City at Etihad Stadium.
A 73rd-minute header from West Brom's Jay Rodriguez doomed United and gifted City the title.
Mourinho said his team had not played the simple football he expects.
"We were masters in complication. Everything was complicated. We couldn't think fast, we couldn't play fast."
