Sakho started the Premier League game at Vicarage Road and played for the entire 90 minutes, as the Reds suffered a 3-0 defeat.
Liverpool legend Carragher was not impressed with the performance of the 25-year-old centre-back, and neither was former Chelsea and Tottenham Hotspur defender Jason Cundy.

We've all had nightmare games but this must be at the top of Sakho's list!!!— Jamie Carragher (@Carra23) December 20, 2015
I know Bogdan is gonna get some stick but Sakho has been a walking disaster all game. Never seen him play well. Not good enough for @LFC— Jason Victor Cundy (@jasoncundy05) December 20, 2015
Over the course of the 90 minutes at Vicarage Road, Sakho had a pass accuracy of 82%, attempted three dribbles, won 40% of his tackles and 83% of his headers, and made three interceptions and eight clearances.
Liverpool’s overall performance against Watford was dire and left much to be desired.
Jurgen Klopp’s side are now five points behind Tottenham Hotspur, who are fourth in the Premier League table and occupy the final Champions League spot.
Liverpool will take on Leicester City at Anfield in the league on Boxing Day.
