City’s Abu-Dhabi owners have splashed an estimated 878 million euros over the past decade to assemble a squad that has tilted the balance of power in Manchester from red to blue.
Kompany was one the Emiratis’ first purchases, and he was a fitting scorer on what seemed destined to be a historic day.
The Belgian outmuscled Smalling to power home Leroy Sane’s corner on 25 minutes.
Five minutes later City doubled their lead in a style that has characterised their season as Gundogan brilliantly turned onto Sterling’s pass before slotting into the far corner.
City should have been out of sight by half-time as Guardiola screamed in frustration after Sterling fired two glorious chances well over the bar.
Unlike in many big games this season, Mourinho played Pogba in his favoured role on the left of a midfield three.

Like the rest of his teammates, Pogba was overrun in the first 45 minutes, but came alive to slot home from Ander Herrera’s cushioned pass with his chest to get United back into the game eight minutes after the break.
That goal was the first Mourinho’s men had scored away from home against top-five opposition in the Premier League all season.
And they soon had two in two minutes when Alexis Sanchez picked out Pogba’s late run into the box and his header beat Ederson low to his right-hand side.
City’s Champions League hopes were likely ended by conceding three times in 19 minutes at Anfield in midweek.
And United took just 16 minutes to complete an incredible turnaround when Smalling capitalised on some slack City marking to turn home Sanchez’s free-kick.
Guardiola threw on Aguero, Jesus and De Bruyne in an attempt to prevent just a second league defeat of the season.
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.
Aguero was denied by a brilliant De Gea save two minutes from time and Sterling then hit the post as United somehow held on for a famous win.
