Of course they wanted to do it today, but they are going to win the title, just not today.
Vincent Kompany opened the scoring for his side followed by Gundogan as City were already 2-0 up by the 30th-minute mark.
With that game in mind, the Spaniard made a decision to keep Kevin De Bruyne in reserve, the Belgian among a powerful bench that also included the fit-again Aguero.
"With City, they love to attack, they don't like to defend, so I had to get more in the box". Guardiola passed on that deal as well, with the Armenian ending up at Arsenal as part of the swap deal which took Alexis Sanchez, 30, to Manchester United.
"What a difference in his second half performance though".
Winning the Premier League never comes easy for City, even in a record-breaking season like this one. But if they thought the game - and the title - were in the bag, they were in for a shock.
Yet just when it seemed United were being outplayed to the point of embarrassment, they launched an astonishing comeback soon after the break with Pogba, previously anonymous despite a new flashy blue hair-do, striking twice in two minutes.
An opening half-hour of few chances produced two goals within five minutes and the title celebrations began - too early.
The French midfielder, who rejoined the Red Devils nearly two years ago in a deal worth £89.3 million, endured a disastrous first half against Manchester City at the Etihad Stadium on Saturday night.
Suddenly the air of celebration had vanished from the stadium but it was to get worse in the 69th minute, with Sanchez again the provider.
Their defenders were as inert in the 69th minute when Smalling was left unmarked to run into the penalty area to meet Sanchez's free kick, volleying the victor past Ederson.
And City should have had a penalty when Ashley Young somehow escaped without punishment from a knee-high lunge on Aguero inside the area that sparked an bad-tempered finale.
