A brace apiece from Gabriel Jesus and Leroy Sane helped Manchester City to a comprehensive 4-0 demolition of ten-man Liverpool at the Etihad.
Kun Aguero gave the host the lead, before the visitors were reduced to ten men following a red card to Sadio Mane.
Gabriel Jesus added a second before the break, before making it 3-0 in the second half.
Substitute, Leroy Sane scored a brace to complete a comfortable afternoon at the Etihad for the host, and move them top of the league, at least temporarily.
The Reds went into the tie in confident mood, having beaten City in four of their last five encounters.
However, despite starting the brightest, only a long range effort from Fernandinho, which Mignolet did well to push for a corner was the only real chance in the first quarter of the game.
In the 25th minute, the home side found the breakthrough, as Kun Aguero gave them the lead.
Kevin de Bruyne picked up Aguero with a delightful through ball and the Argentine forward rounds Mignolet before slotting into an empty net.
Twelve minutes after going behind, it got worse for Liverpool as they were reduced to ten men, following Sadio Mane’s sending off for a dangerous foul.
A loose ball sent in from the Liverpool half was chased by Mane and Ederson, who headed the ball clear only to be knocked out by a high Mane boot, and the referee had no option but to send the Senegalese off.
Ederson was subsequently stretched off and replaced by Claudio Bravo in goal.
Just before the break, City doubled their lead through Gabriel Jesus, who was set up by De Bruyne, who sent in a perfect cross from the left that the Brazilian heads past Mignolet, after he was left unmarked.
After the break, whatever Liverpool players were told was obviously not working as they found themselves 3-0 down.
Fernandinho found Aguero, who unselfishly squares up for Jesus to convert past a helpless Mignolet in goal for Liverpool, who were looking rather bereft of any ideas.
City continued to dominate and create chances, with Pep Guardiola going for the kill when he substituted Jesus for Sane.
Liverpool also made their own change, pulling off Georginio Wijnaldum for James Milner, their second of the match after initially bringing on new signing, Alex Oxlade-Chamberlain.
With a man advantage, City were in control and it went from bad to worse for Liverpool, who were made to pick the ball from the net for the fourth time, when Sane met a low cross from Benjamin Mendy to give City a 4-0 lead, after a fine finish.
In stoppage time, if the result was ever in doubt, Sane cleared those doubts when he sent City top of the log with a beautiful goal to complete a 5-0 rout, which sends the Cityzens temporarily top of the log.
