It's not often Liverpool fans will become full with anxiety and trepidation while watching Manchester United get thumped, but to see a Manchester City side - who an out-of-form Reds play in two weeks - rip their old rivals to shreds must be cause for concern.
Pep Guardiola's champions already look well on course for a fifth title in six years and remain unbeaten in the league after eight games. Erling Haaland bagged yet another hat-trick to take his tally to 13 goals in eight appearances - the 22-year-old is bordering on a cheat code at the Etihad, where he has three consecutive league hat-tricks.
While Arsenal have enjoyed a similarly imperious start to the new campaign - they are a point ahead of City - it's hard to see anyone keeping up with the Sky Blues for the remaining 30 games, not least a Liverpool side who look bereft of energy and confidence. It is testament in itself that Jurgen Klopp's team pushed City so far over the last five seasons, even pipping them to an illustrious first Premier League title in the 2019/2020 season.
