The loss handed City the title, leaving United trailing by 16 points with five games remaining, and Mourinho immediately faced the question of whether he was confident his team could make a real challenge next year.
"The commitment, the desire, and I asked if Pogba can do that all the time, the way he played against City". I think in my experience you don't win titles with inconsistency, you win titles, of course, with quality, without quality you have no chance, but you win titles with consistency at every level.
Mourinho claimed afterwards that he had not been happy after the City result because he knew they would win the league regardless and he accused some of his players of getting carried away.
"I saw lots of people in the moon because we won against City".
Juan Mata echoed comments from Mourinho, accepting United were far below the required standard in defeat to West Brom.

Else, sources said, the government could just bring amendment strengthening the SC/ST Atrocities Act. "The judgment has diluted the provisions of the Act, resulting in great damage to the country".
"We were masters in complication, everything was complicated", Mourinho added. We could not play fast, we could not think fast, everything was complicated. Players didn't play simple. "It is one of the things that we have to improve".
"We did not deserve to lose, but we gave them the opportunity to win the match".
Pogba had found himself benched by Mourinho last month and the United boss believes the 25-year-old - whose future was the subject of speculation in the build-up to him spoiling City's planned title party - can be more consistent.
"I don't know if I was the first or second or third but I congratulate them face to face when I had the chance", Mourinho said.
"I have won titles, I would not be happy if someone said I won title because someone lost a match".
United gifting City the title by losing to West Brom came just a week on from them delaying their rivals' celebrations.
