Alan Shearer believes Liverpool's supporters were louder than he ever heard them against Dortmund.
Shearer is no stranger to playing at Anfield, taking them on numerous times throughout his career and even playing his 300th professional game at the stadium.
The BBC Match of the Day pundit says the support against Dortmund was impressive and deserved the performance the team provided in response.
"Liverpool appear to be finishing the season strongly. It was an amazing game on Thursday evening where they came back from 3-1 down to beat Dortmund.
"I’ve been privileged enough to play at Anfield many times but I don’t think I have heard The Kop sing You’ll Never Walk Alone as loud as that.
"The atmosphere was just amazing and the game lived up to that."
Liverpool won the game 5-4 on aggregate with Dejan Lovren's injury time winner resulting in an outpouring of noise and emotion, with the Reds progressing into the semi-finals of the Europa League. Liverpool had been 4-2 down on aggregate with half an hour remaining of the tie.
A Champions League place is up for grabs for the winner of the competition, but whatever happens in the latter stages, the memory of the comeback last week will live for a long time.
