When the Premier League fixtures came out in the summer both Pep Guardiola and Jurgen Klopp would probably have circled this as a title decider.
And it might well turn out to be just that. For Manchester City, anyway. The reigning champions served notice to Arsenal that they are not going gently into the same dark night that appears to have swallowed Liverpool whole.
After Mo Salah had scored his customary goal against them, City were inspired to take the Merseysiders apart. Even without Erling Haaland. Julian Alvarez equalised before Kevin De Bruyne, Ilkay Gundogan and Jack Grealish also found the back of Alisson Becker’s net in the second half.
