Now, the new Premier League champions can focus on breaking records with nine more points required to beat Chelsea's record tally of 95 set in 2004/05 and three wins to break the Blues' record set last season of 30 wins in a single campaign.
City boss Pep Guardiola had planned a day of golf with his son Marius on Sunday, so the Spaniard might have learned of his first Premier League while on the course. Manchester City ended their three-match losing run with a convincing win over Tottenham at Wembley Stadium.
They also hit four past Tottenham, six past Watford and seven past Stoke City in huge wins before Christmas, while also winning 2-1 away at rivals United in December as they also finished top of their Champions League group.
Going into the game off the back of a thrilling comeback against City, United were expected to further halt their noisy neighbours' title charge with a win against Championship-bound West Brom.
It's the third Premier League success for the club following the titles won in 2012 under Roberto Mancini and 2014 under Manuel Pellegrini with captain Vincent Kompany, David Silva, Sergio Aguero and Yaya Toure involved in all of them.
Ex-United defender Jonny Evans is a doubt for West Brom with a knee injury.
City did not lose a game until January against Liverpool, and drew just twice until that memorable clash at Anfield, while smashing five past Liverpool at the Etihad early in the season, as they stunned opposition, supporters and critics alike with their performances.
Eight minutes later, United managed their first real foray into the box when Romelu Lukaku found himself in space 16-yards out, but his stinging shot was brilliantly saved by Ben Foster. United have won their last five league matches.
They clinched the silverware 24 hours later thanks to Albion forward Jay Rodriguez's 73rd minute header at Old Trafford.
That could see Juan Mata recalled while Marcus Rashford may get the nod ahead of Anthony Martial amid rumours both players are becoming unsettled due to a lack of regular starts.
