The Reds found themselves 3-0 down to AC Milan in the first half of the Champions League final but produced one of the greatest comebacks of all time to draw level at 3-3.
That forced extra time, in which Dudek made an unforgettable double save against Andriy Shevchenko - and then a penalty shoot-out, in which Dudek starred to give LIverpool their fifth European title.
And the 40-year-old admits it was defender Carragher who spurred him on before the shoot-out and reminded him of Bruce Grobbelaar's famous match-winning tactics in the 1980s.
"I did a little bit of Bruce Grobbelaar," he told Goal. "If you watch the games, [Bruce] was out of power then immediately he went to save the penalty and I had that in my mind.
"But Carragher came to me just before the penalties and he jumped on my back, he was pushing me like 'Do something, put them under pressure, please put them under more pressure, I don’t know... like Grobbelaar did, you remember'. I said, 'Okay but give me a few seconds because I got the book, and I need to study my penalties.'"
Former Poland goalkeeper Dudek also spoke of the "power" and inspiration he drew from the fans, who passionately sang 'You'll Never Walk Alone' at half-time despite seeing their side go 3-0 down.
"I recognised that all the people started to stand up and sing 'You'll Never Walk Alone' and I said 'what are they doing? We're losing 3-0!'
"Afterwards, I spoke to a few of the people that were in the stadium and they were shouting to each other 'eh, come on, this is our day, this is the day we want to be here, we have to enjoy ourselves.'
"That song gave us more power, even in a difficult situation."
Liverpool have a strong tradition of penalty-saving goalkeepers, from Grobbelaar's original 'wobbly legs' in the 1984 European final against Roma, to Pepe Reina, who succeeded Dudek and won the 2006 FA Cup on penalties with the Reds.
Most recently, Brendan Rodgers' number one goalkeeper, Simon Mignolet, introduced himself to the Kop by saving a spot-kick against Stoke City on his debut. The Belgian's save was vital in ensuring Liverpool got all three points and started the season with momentum on their side.
Was the 2005 Champions League final Liverpool's greatest ever moment?
