Liverpool was made to work extremely hard for the result. Still, they ultimately found the breakthrough, narrowly getting by Nottingham Forest in the FA Cup quarter-finals thanks to Jota’s toe-poked finish after 78 minutes.
It seemed a matter of time until the visitors would find the opening goal, such was their superiority.
But Cooper’s side kept the opposition honest, occasionally hitting on a rapid counter-attack through Johnson or Davis.
The best game chance for the hosts fell to Zinckernagel at 0-0, but he was unable to convert from close range, giving Jota a chance to seal the deal two minutes later.
The win sees Liverpool go on to the semi-finals where they will play Manchester City, while the competition ends for Nottingham Forest.
NOTTINGHAM FOREST XI (3-4-1-2): Ethan Horvath;
Jack Colback, Tobias Figueiredo, Joe Worrall;
Joe Lolley, James Garner, Ryan Yates, Djed Spence; Philip Zinckernagel;
Keinan Davis, Brennan Johnson.
NOTTINGHAM FOREST SUBS: Braian Ojeda, Sam Surridge, Alex Mighten, Brice Samba,

LIVERPOOL SUBS: Thiago, Joel Matip, Adrian, Curtis Jones, Luis Diaz, Divock Origi,

LIVERPOOL TAKE THE LEAD! 1-0! Tsimikas wraps a right-footed cross to the far post looking for the run of Jota, who does just enough to remain onside before lunging at the delivery and steering it past Horvath with a toe.
