Liverpool faced AC Milan in the Champions League final over 13 years ago, where they pulled off one of the greatest footballing comebacks of all time.
Paulo Maldini gave the Serie A giants an early lead before Chelsea flop Hernan Crespo bagged a sublime brace.
Liverpool then came roaring back, however, with Steven Gerrard getting the ball rolling with a pinpoint header.
Vladimir Smicer and Xabi Alonso then struck to level the scores before Dudek made himself a hero in the penalty shoot-out.
The former Poland No 1 made the decisive save from Andriy Shevchenko.
And Liverpool then scooped the prize, leaving then-Milan manager Carlo Ancelotti stunned.
Dudek has now revealed the advice given to him by Carragher before his Istanbul heroics.
“Ancelotti isn’t angry with me, I met him after the final against Milan and we talked a lot,” Dudek said on Radio Crc.
“Milan practically had that game won, so much so that Ancelotti declared it was the best first half of one of his teams, but in the end they lost. Seriously, it was an amazing comeback.
“I didn’t plan my dance on the penalties, but there is a background to it. Jamie Carragher told me to come up with something to distract the Milan players.
“I refused because I wanted to be focused, but he was insistent so I tried it with the first penalty. It worked, so I kept doing it and I was moving more and more with each penalty.
“I tried it again in my career and it doesn’t always work, but it certainly puts more pressure on the opponent.
“I was very confident in that final thanks to my double save on Shevchenko.”
Dudek was speaking ahead of Liverpool’s Champions League clash with Napoli tomorrow.
“I know Ancelotti and I really respect him. When he took over from [Jose] Mourinho at Real Madrid he led the team to the Champions League,” he added.
“I think Napoli bet on him to break the Juventus hegemony.”
