Argentine superstar Sergio Aguero scored the first for City which incidentally also took him past Dwight Yorke as the leading non-European Premier League goalscorer of all time before Liverpool's Sadio Mane was sent off for a reckless challenge on City keeper Ederson.
Sadio Mane was dismissed after his raised foot collided with the face of City keeper Ederson, who required 10 minutes of treatment on the pitch.
Manchester City playmaker Kevin De Bruyne would be an automatic pick in every Premier League team, according to Jamie Redknapp. He deserves a second chance and with Mane suspended, he may just get that chance very soon. He learns, he's so intelligent.
"He produces a huge (number) of passes and assists". Last season he shot 15 or 16 times against the post. They have players who can change games and make chances.
"He's quick, always he sees the spaces in the middle [and] outside more than anyone else", Guardiola said. He runs more than anyone else.
"A complete, complete player". He loves to be here with us.
"I think we handled it really well".

"This season he's in a good mood, maybe because he is a father". He's one of our captains.
"I am very happy!" he said. "And not just today".
The Brazilian got his brace and City's third of the afternoon in the 53rd minute.
The Man City goalkeeper was in town for a meal with his nearest and dearest in Deansgate, hours after he was booted by the Senegalese.
"In the system we play at the moment - it's not fixed for the next seven or eight months - he can play in four positions: as both number eights and both wingers".
"But we didn't, and that's what the first half was like, we weren't compact enough and didn't cause them enough problems".
And it came when the game was still 11 vs. 11. "Phil is a fantastic player, and hopefully we can use him as quickly as possible".
Although the dismissal handed Pep Guardiola's men the advantage, Klopp believes Liverpool's backline, which has come under scrutiny in recent weeks, was left exposed by the failings of the side's midfield unit - even before Mane's sending off.
