They trail the Cityzens 2-1 at half-time.Title implications are at stake at the Etihad Stadium as the Reds face City. However, it is Pep Guardiola's men who currently sit in the driving seat.An early Kevin De Bruyne strike was canceled out by an accomplished Diogo Jota finish following Alexander-Arnold's pull back.But then a lapse in concentration by Alexander-Arnold allowed Gabriel Jesus to creep behind and capitalize on a beautiful sweeping cross from Joao Cancelo.The tie has been a cagey affair with City making the most of questionable defending by the Reds. A City win would tilt the title-race firmly in their favour.Liverpool fans fumed at half-time at Alexander-Arnold's error-ridden performance.See some of the reactions from fans below:Akash@akashag6797Thank god he made that assist because this has been absolutely horrendous performance from Trent.5:00 PM · Apr 10, 20221Thank god he made that assist because this has been absolutely horrendous performance from Trent.ً@utdcynicalCancelo’s been unreal.

However, he has not shown the impressive form that has preceded him in recent times.His lackadaisical reaction to City's second, where his lapse in concentration allowed Gabriel Jesus to score, was astounding.It meant Liverpool went in at half-time trailing an opponent for the first time this season in the Premier League.Jurgen Klopp will surely be getting into his players at half-time, telling them to concentrate and not let the pressure get to them.Even Virgil van Dijk, who is usually a stable figure, has been nervy. Going forward, Klopp's men have been threatening. Mohammed Salah looked up for the occasion and Jota's inclusion paid off with his goal.But it was Manchester City who have been the better side for large portions of the first-half. They look to be consolidating their place at the top of the Premier League.De Bruyne, Cancelo and Jesus are breaking through the Anfield side's defense and causing havoc.The second-half promises to be a mouthwatering affair and Alexander-Arnold and the Reds need to react.
