The Reds claimed an impressive victory in front of their home fans at Anfield as goals from Fabinho, Mohamed Salah and Sadio Mane secured the three points for Jurgen Klopp’s men.
Bernardo Silva’s consolation goal was not enough for the visitors as Pep Guardiola’s men crashed to their third Premier League defeat of the season.
The result left Liverpool FC flying high at the top of the Premier League table and eight points ahead of Leicester City and Chelsea FC.
Manchester City, meanwhile, are now a further point behind the Reds in the title race after 12 games of the new campaign.
Defender Robertson has warned his team-mates that the title race is far from over, but he admitted that it always feels good to beat one of your closest rivals.
Speaking in an interview with Liverpool FC’s website, Robertson said: “Massive for us. A big game against our closest rivals from last year.
“Both of us were in a league of their own last year and it looks as if there’s going to be a couple of others sniffing about this year. But I still believe if you finish above Man City then I think you’ll get the title.
“It’s a massive win for us and it’s just another one that we’ve got to tick off. There’s still a long, long way to go, but it’s always nice to beat your rivals.”
Liverpool FC will return to Premier League action after the international break when they take on Crystal Palace away from home.
