#4 Dejan Lovren's nightmarish performance
Dejan Lovren was handed his first start since December but, at the end of 90 minutes, it was clear to see why most Liverpool fans would rather see the back of him.
He had dropped a clanger in the 2-2 draw with Shrewsbury in the FA Cup, and did little to redeem his battered image with another sub-par display against Watford.
The Croatian international was not strong enough on Abdoulaye Doucore in the buildup to the opener, and was caught of position for the other two goals.
The 30-year-old former Southampton man was far from alone, however, with the normally dependable Virgil Van Dijk also at fault for the first goal, alongside Andrew Robertson, while the second and third Watford goals also came about after lapses in concentration.
While Dejan Lovren might be the biggest scapegoal of this defeat, the bottom line is that Liverpool were simply not good enough defensively, and Watford were good value for their victory.
