Liverpool were made to work hard for a share of the spoils at Anfield, twice coming from behind before Victor Munoz's stunning strike secured a 3-3 draw against a resilient Nottingham Forest side.
Forest struck first when Dan Ndoye finished expertly past Alisson, ending a 377-day wait for a Premier League goal. The move stemmed from Matz Sels' long clearance and Igor Jesus's strong hold-up play, which allowed Ndoye the space to fire home. Alisson had already been called into action moments earlier, producing a superb save to deny Jesus a certain goal just before the half-hour mark.
Liverpool responded through Florian Wirtz, who had a neat finish chalked off after Jeremie Frimpong was caught marginally offside in the build-up. The German playmaker was a persistent menace throughout, also seeing a header tipped over by Sels, before eventually turning provider for Munoz's equaliser.
The hosts drew level for the first time when Alexander Isak, largely anonymous for much of the afternoon with just six touches and no shots in the first half, converted from close range on the hour mark after Cody Gakpo's teasing cross found him at the back post. It was only Isak's ninth touch of the match, but the finish will do wonders for his confidence after a quiet start.
Forest's response was swift and clinical. Neco Williams won a penalty following a challenge from Alisson, and Morgan Gibbs-White stepped up to convert it in style, restoring the visitors' lead and continuing his fine record at Anfield. The midfielder now has five goal involvements at the ground - three goals and two assists - and has scored more Premier League goals than any other Englishman this calendar year, with 13 to his name.
Liverpool refused to give up, and it was debutant starter Munoz who produced the moment of magic to salvage a point. Making his first start for the club down the left flank, the Spaniard curled home a brilliant effort in front of the Kop to make it 3-3, capping an impressive full debut in which he had already gone close with a first-half effort and had a penalty appeal waved away.
Both sides made changes as the game wore on. Liverpool brought on Kostas Tsimikas, Ryan Gravenberch, Rio Ngumoha, Rafael Araujo and Trey Nyoni in a flurry of substitutions, while Forest introduced Cyriel Dessers... no, Taiwo Awoniyi did not feature, though Delap replaced the scorer Ndoye and further changes saw Nicolo Netz, Callum Hudson-Odoi and Dominguez introduced late on.
Elsewhere on the pitch, Ola Aina and James McAtee both impressed for Forest, with Aina relentless in his energy down the right and McAtee tidy on the ball after stepping into a more prominent role following Elliot Anderson's departure to Manchester City. Xaver Schlager also acquitted himself well in only his early days at the club, deputising for the injured Ibrahim Sangare.
For Liverpool, questions remain over defensive frailties, with Virgil van Dijk and the backline again caught out for a goal conceded, while Milos Kerkez struggled on the left before being withdrawn. Gakpo, in what could prove to be his final appearance for the club, showed both promise and lapses, but his assist for Isak's goal underlined his quality.
The result leaves both sides with plenty to reflect on as a pulsating six-goal thriller ended honours even.
