**Second half**
Liverpool started on the front foot after the change of ends as they looked to level the contest quickly.
Their pressure was met by an impressive Forest defence, who held firm and limited any clear opportunities for the home side in the early exchanges.
The Reds, however, found a way back onto level terms on the hour thanks to a brilliant turn and cross from Gakpo on the right flank.
The winger was sent on his way by Wirtz as he spun two defenders to deliver a low ball across the six-yard box for Isak to tap home at the back post.
Liverpool continued to dominate the ball, but the next major moment came for the visitors with 20 minutes remaining.
A quick attack saw substitute Liam Delap take a quick throw-in from the left, which allowed Williams to advance into the Reds penalty area.
The defender got to the ball and flicked a shot goalwards, though the onrushing Alisson was adjudged to have taken him down with a penalty awarded.
Visiting captain Gibbs-Whites stepped up to duly convert from 12 yards and restore Forest's one-goal advantage from the spot.
Iraola responded with a number of substitutes as Liverpool looked to find another levelling goal in the game.
However, it was two players already on the pitch who combined to find the important goal with eight minutes remaining.
Dominik Szoboszlai slipped a pass into the feet of Munoz on the right side of the box, with the forward spinning and striking an effort into the back of the net via the underside of the bar to spark celebrations.
The Reds then searched for an all-important winner as Szoboszlai whistled a free kick past the far post, though they were forced to settle for a battling point in L4.
