Kongolo turns it into his own net, but that goal was all Leroy Sane! 6-1.
Jon Gorenc Stankovic gave the visitors the slightest glimmer of hope before half time when he poked in from Steve Mounie's flick-on, but any optimism was snuffed out early in the second half by a brilliant free-kick from David Silva.
With no Kevin De Bruyne for the next three months, it seems like City may be able to cope just fine without their magic attacking midfielder. Some excellent stops by the inundated Hamer and a few obvious misses halted the score from hitting double figures with City enjoying 77 percent of possession and revelling in 32 shots at goal.
Top of the highlight reel in the latest exhibition by City was a 70-meter pass from goalkeeper Ederson Moraes from his own penalty area that found Aguero running behind Huddersfield's defensive line.
He added: "When I read sometimes and watch sometimes, it looks like we finished sixth or seventh and everybody did better than us".
Bernardo Silva is the most likely candidate to step up for the Citizens in De Bruyne's absence and he enters this weekend's clash with Huddersfield Town in decent form, scoring the second goal in last week's 2-0 victory over Arsenal.
At half time Laurent Depoitre came on for Huddersfield as they switched up their formation to a 4-4-2. Silva curled home a majestic free kick with his left foot to mark his 250th appearance for City in style.
At the final whistle, Aguero said: "Hat-trick number 13? Wow".
Of course, with so long left, it was nearly inevitable that the Blues would inflict further damage and it came on 75 minutes as Mendy sent in a fine low cross and Aguero deftly volleyed past Hamer from close range for yet another hat-trick in sky blue. "With the problems we had before the game, it didn't make it easy for us and we have to say congratulations to City for a great performance, we were not good enough today".
Two wins from two at a canter for Guardiola's boys.
