Three goals down at halftime, the Reds stormed back to draw with AC Milan 3-3, before beating them on penalties in the 2005 final.
Former Reds striker Cisse told RMC: "Stevie gets up and says that Liverpool is all he has.
"It is his club, all he has ever known and he does not want to be the laughing stock of the history of the Champions League.
"He says if we respect him and love him as a captain, then we need to dust ourselves off and get back in the match.
"He scores the first goal, he gets the penalty. He has an extraordinary second half, finishing the game as a right-back.
"He has a crazy match – but that half time speech will remain imprinted in my mind forever."
