United had beaten City in a stunning comeback during the derby, denying them the title, but denied that win was the most important win of the season.
Manchester United struggled to cut through Albion's compact defence and when they did found an equal in former goalkeeper Ben Foster, who blocked from Romelu Lukaku at point-blank range and kept out Alexis Sanchez's follow-up with his legs.
"I had a feeling when I woke up this morning", Kompany said.
We were masters in complication.
A disappointed Juan Mata says Manchester United must shift their focus to a crucial week in their season following their 1-0 loss to West Brom on Sunday. The United side of 2000-01 and Everton's 1984-85 team also won the title with five games to spare.
City must have been quite disappointed to watch Chelsea and Leicester City win the last three Premier League titles, but they are finally back at the summit, drowning out painful memories of their midweek Champions League exit at the hands of Liverpool. They lost only two matches, that is why they were champions. Eight titles are eight titles and three Premier Leagues are three Premier Leagues.
"Everything was one more touch, one more flick, one more pass, one more touch", Mounrinho added.
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.
"We are a team that has already more points than last season, a team that's had brilliant matches and a team that showed character many times".
"It was not done even if we won", he said.
"I don't know if I was the first or second or third but I congratulated them face to face when I had the chance", Mourinho said.
Jay Rodriguez netted the lone score for West Brom.
According to Red Rants, Ander said: "I am going to fulfil the year that I have left but I don't know if I will renew".
