The Reds headed into the final day of the 2018-19 campaign more in hope than expectation.
Jurgen Klopp’s side knew that they were looking for favours from afar, with Brighton needing to halt the charge of Pep Guardiola’s defending champions at the Amex Stadium.
The Seagulls did briefly lead, after Sadio Mane had opened the scoring against Wolves at Anfield, but City surged back to claim the crown with a 4-1 win.
That setback did, however, come away at City – having previously been held to a goalless draw on home soil in a game which saw Riyad Mahrez sky a late penalty.
Carragher admits those results ultimately cost the Reds dear, telling Sky Sports: “Liverpool have a manager who is an optimist and will feel he can challenge again next season, but if City are going to get 96, 98, 100 points it’s very difficult to stop.
“The only thing Liverpool can look back with at regret is they didn’t beat City.
“You can’t expect other people to take points off City if you don’t do it yourselves and Liverpool only took one from six against City.
“Next season they have to look at those games as cup finals and beat them, although that's easier said than done!”
Carragher added on City, who added 98 points this season to the record-breaking haul of 100 they managed in 2017-18: “This Man City team is something extraordinary.
“You can understand the Liverpool players and manager will be a bit flat as when they look back on this they would want something to show for their efforts.”
The Reds can still end their campaign on a high.
