The match was blown open in the final 20 minutes, helped along by crucial giveaways from the Reds goalkeeper.
A pair of mistakes by goalkeeper Alisson was the difference as Liverpool fell 4-1 at home to Manchester City on Sunday.
Ilkay Gundogan and Raheem Sterling were the beneficiaries of Alisson's blunders, which came at 73 and 76 minutes, respectively, after the teams were tied 1-1 and seemingly on the way to a draw. Gundogan also had a 49th-minute strike as he redeemed a first-half penalty miss, while Phil Foden added an exclamation mark to City's victory seven minutes from full time.
Liverpool managed to keep things interesting for most of the match, with Mo Salah's emphatic penalty putting the teams on level terms just after the hour mark. Still, City's opportunism combined with Alisson's ill-fated giveaways were the story of the match.
The result sees City go five points clear at the top of the Premier League standings, while fourth-place Liverpool missed an excellent opportunity to make up ground on the teams ahead of them.
It hasn't been too eventful a half, but some big moments have defined the opening 45 minutes. Gundogan's miss will be the talking point, but Liverpool taking 24 minutes to get a look at goal should not be forgotten.
All in all, an entertaining opening half of football.
