It was a superb performance from the home side, who pushed Liverpool right from the first whistle and really took the game to them.
Taiwo Awoniyi, a former Liverpool player, scored the only goal, with his initial shot hitting the post before he tapped in from close range.
From the high of beating Manchester City last week to suffering their most embarrassing defeat of the 2022/23 campaign today, it’s been a rollercoaster for Jurgen Klopp this season.
There were a host of poor performances, with Fabinho winning just one duel all match, however, it was youngster Fabio Carvalho who failed Klopp’s big test today.
The summer arrival, who has made a positive start to his Anfield career, already scoring two Premier League goals, let Klopp down against Forest.
The 20-year-old received a lowly SofaScore rating of 6/10, the lowest on the pitch, and his inexperience perhaps caught him out this afternoon.
Carvalho took just 28 touches during his 62-minute spell on the pitch, one less than Alisson, and completed only nine passes, far below the standard that is required at Liverpool.
He did attempt to contribute going forward, but only one of his four shots hit the target and this lack of composure clearly cost the side.
Defensively, the player wasn’t much better, winning just 25% of his total duels while losing possession 11 times, as well as making just two tackles during his time on the pitch.
It was an uncharacteristically poor performance from the much-heralded talent and he will learn from experiences like this going forward.
If the result against City last week gave the German manager some hope that a comeback could be on in order to offer a title challenge, then today’s defeat surely buries those ambitions.
A Champions League tie against Ajax comes next on Wednesday, and it could be the ideal match to redeem themselves following this horror show in Nottingham.
