Forest twice took the lead, first through Dan Ndoye and then through Morgan Gibbs-White as it searched for a third consecutive win at Liverpool, but Alexander Isak and Munoz struck to clinch a draw for Andoni Iraola's side.

Liverpool struggled to cope with Forest's early pressure and had to thank Jeremy Jacquet as he denied Igor Jesus with a last-ditch block in the six-yard box, while Ndoye missed the target with a header from James McAtee's deep cross.

However, Ndoye curled into the bottom-right corner in the 24th minute after Liverpool was undone by Matz Sels's long ball down the middle, which eventually led to Gibbs-White teeing up the Swiss international.

Wirtz thought he levelled for Liverpool just eight minutes later as he finished on the swivel, but the goal was ruled out because of an offside against Jeremie Frimpong in the build-up, while the German also saw a header palmed over by Sels before half-time.

Alisson expertly kept out Jesus's first-time effort before the break, and it proved crucial as Isak levelled on the hour after Cody Gakpo spun past Neco Williams and picked out the Swede with a low centre.

However, the Brazilian conceded a penalty 10 minutes later as he brought down Williams, who capitalised on a quick throw-in from Liam Delap, and Gibbs-White made no mistake from 12 yards out.

But just as he did against Newcastle United last weekend, Munoz made the crucial impact for Liverpool with a stunning strike on the turn to restore parity in the 82nd minute.

"I think we improved a lot in the second half. We were much more intense, much quicker on the ball, with more sense of urgency," Iraola said after the game.

"But it's not enough to win the game, and I think we have to blame the first half that we had."

A bigger concern for Iraola is Liverpool's tendency to start slowly, a habit it has carried over from last season.

While he was encouraged by the character shown to recover from a losing position for a second consecutive match, he believes the underlying issue lies in his side's work without the ball.

"In the first half we were being passive without the ball, leaving a lot of distance and becoming a little bit comfortable," he said.

"When we improved the intensity, we won more duels and started attacking quicker and attacking better. This lack of intensity without the ball has hurt us."

Forest boss Oliver Glasner was proud of his side's performance, despite blowing the lead twice.

"Overall, the performance was top, especially in the first half, creating so many chances here at Anfield," Glasner said.

"I really loved the reaction after we conceded the equaliser, we still played forward and were rewarded with the penalty.

"We feel proud of the performance – but also disappointed with the result. This tells us a lot. A lot of positives to take but still a lot of work to do.

"This is exactly what we needed after two tough defeats at home to Leeds – we had lost a little bit of confidence. 

"This group has an amazing character, and I told them, 'When nobody believes, it's important that you believe.'"
