Liverpool staged a second-half fightback to come from behind and beat nine-man Brentford at the Gtech Community Stadium
Previously unbeaten Brentford paid a heavy price for the red card given to Yehor Yarmoliuk in first-half added time for a "headbutting action" - in the words of referee John Brooks - on Liverpool defender Jeremy Jacquet.
Keith Andrews' side were a goal up through Keane Lewis-Potter's superb 44th-minute header, and in control, when Yarmoliuk was dismissed - but Liverpool made the most of their numerical advantage to launch a comeback after the break.
Spain winger Victor Munoz scored a fine equaliser after 62 minutes, cutting inside to beat Brentford keeper Caoimhin Kelleher with a left-foot finish after he was released by Florian Wirtz's pass. Alexander Isak added the second eight minutes later with a clinical strike for his fifth goal of the season, after Bradley Barcola headed down Alexis Mac Allister's cross.
Brentford's day of frustration was complete when they were reduced to nine men in stoppage time - Vitaly Janelt shown a second yellow card for a foul on Liverpool substitute Rio Ngumoha.
