London, Nov 22 (IANS): New manager Juergen Klopp saw the best result since his arrival to Liverpool as the Reds beat Premier League title chasers Manchester City 4-1.

A stunning first-half display of high pressing and counterattacking saw Klopp's side, which move to within six points of a Champions League berth, surge into a three-goal lead at the Etihad Stadium on Saturday, reported Xinhua news agency.

It was the first time since February 2003 that City had conceded three goals before the interval in a league fixture.

First-half goals from Brazilian duo Philippe Coutinho and Roberto Firmino stunned the hosts which had fallen behind after Eliaquim Mangala put through his own net.

Firmino enjoyed his best performance in a red shirt since joining the club from German side Hoffenheim for a reported fee of 29 million pounds ($45.8 million). He was flanked by compatriot Coutinho, who continues to thrive under Klopp. The pair were involved in all three goals as Liverpool established a firm hold on the game.

Fit-again striker Sergio Aguero pulled one back shortly before the interval, curling a splendid effort beyond Liverpool goalkeeper Simon Mignolet.

City slipped to third on 26 points, two adrift of new league leaders Leicester, while Liverpool move up to ninth with 20 points.
