Alex Oxlade-Chamberlain has conceded Liverpool were aware of Brentford's key strengths ahead of yesterday's defeat but failed to rise to the challenge of nullifying threats posed by Thomas Frank's side.
Undone by set-pieces and balls being played into the box, the Reds suffered the same outcome as when the sides met at the Gtech Community Stadium last season despite being spared having to handle the prolific Ivan Toney.
Brentford's first and second goals came from headed efforts Alisson could not keep out and saw two additional set-piece goals ruled out by VAR, sparing Liverpool's blushes before the break.
