Liverpool won 1-0, with Luis Garcia grabbing a winner that Chelsea boss Jose Mourinho maintains was not a goal.
Mourinho also insists the Reds were not the best team in Europe last season, despite winning the competition.
In the Reds camp, their manager Rafael Benitez believes the Blues' desire for revenge may work against them.
Chelsea feel that Garcia's effort did not cross the line in the second leg at Anfield.
The Reds, however, would counter that Blues keeper Petr Cech would have been red-carded and their side awarded a penalty for a foul on Milan Baros if the goal had not been awarded.
"They didn't score in the semi-final against us but I accept they beat us," said Mourinho. "They played in the final and we stayed at home, so of course I accept it.
"I was upset at that time but not any more. They beat us but they didn't score. I will say that for all my life but it doesn't mean I am sad.
"There are certain highlights in your career that you never forget and I won't forget the goal nobody saw.
"In five matches, we beat them three times, they beat us once and we drew once. The game at Anfield, where everybody says they beat us was, I think, a zero-zero draw."
And Mourinho believes the introduction of goal-line technology would put an end to the disagreements.
"Using simple technology we could put a stop to wrong decisions," he said.
"The use of chip technology in the ball - which works through the transmission of a sound signal - would confirm if the ball crossed the line or not.
"It is so simple to resolve and yet these errors keep happening."
And Mourinho insists that Liverpool were not the best team in the competition last season.
He added: "Nobody can prove who is the best team in Europe but I do not believe it was Liverpool last season.
"Many times the Champions League winner is not the best team in Europe. I believe Barcelona played the best in the competition last season.
"When I won the competition with Porto we didn't have to face AC Milan or Real Madrid."
The meeting between the two is the first in five days as the pair will also face each other at Anfield in the Premiership on Sunday.
And Reds boss Benitez said: "I do not know whether Chelsea are putting more pressure on themselves by talking of revenge but you can hear these words from them.
"But the most important thing for us is to prepare for the game and not to talk a lot about other things like this.
"We will prepare well against a good team and concentrate for 90 minutes. Chelsea do have weaknesses, for sure, every team has.
"They are beatable and we have an idea of how to win.
"I do not care when people say Chelsea are favourites, even though we are champions.
"All I will do is prepare my team the best way we can, to have confidence and to know we can beat them."
