City could have won the title against United last weekend but had to wait after surrendering a two-goal lead at the Etihad and handing Mourinho's team a stunning 3-2 comeback victory.
City's supporters are now discovering that winning the title without even playing, courtesy of West Bromwich Albion's unexpected 1-0 victory at Old Trafford on Sunday, does nothing to diminish the joy of planting your flag at the summit while the rest look on enviously below you.
Jay Rodriguez headed home the only goal of the game to keep their faint relegation survival hopes alive.
"You could see the difference in attitude to players compared to last week".
"We always gave them the opportunity to be solid, compact, together with huge physical strong players, they always had time to organise themselves".
More importantly, though, it means Pep Guardiola's City team can not now be caught at the top of the table, thus handing the Catalan coach his first Premier League crown in just his second year in English football.
It's been nearly inevitable for the whole of 2018 but Manchester City have today sealed the Premier League title without even kicking a ball on Sunday afternoon. Eight titles are eight titles and three Premier Leagues are three Premier Leagues.
Guardiola's side have only dropped points against Burnley and United since the New Year, while marching into an explosive Champions League quarter-final with Liverpool that saw them knocked out earlier this month.
"They won because they were the best team, they lost only a few points. As I was saying, eight titles are eight titles and three Premier Leagues are three Premier Leagues and the last Premier League was not 20 years ago, was three years ago", Mourinho was quoted as saying by Reuters.
Can United be more competitive next season?"Everything was complicated. Players they didn't want to or couldn't play simple", Mourinho told SkyTV afterwards. They gave a superb response with a swaggering win at fourth placed Tottenham.
WE SHOULD HAVE HAD A PENALTY IN THE FIRST HALF "Paul Tierney [the referee] was unlucky in one decision [the challenge by Craig Dawson on Ander Herrera] but I don't blame him at all - it's football".
