After Fernando Torres had grabbed the second-half winner, Benitez said: "I do not have any preference now who we play next, but I would be more than happy to face an English side in the final.
"This victory shows the power and strength of the Premier League. We have fine clubs who are amongst the best in Europe, a league that is the same and players of quality who are some of the best in Europe."
Benitez won the tactical battle but admitted the sending-off of Nicolas Burdisso early in the second half had changed the game.
He said: "The two goals we scored in the first leg were crucial, and then when they had a man sent-off it is always easier to play against 10 men than 11.
"The key for us was to be compact in the first half when they were attacking and to be sure that we hit them on the counter-attack.
"This is the third time we have got to this stage while I have been at Anfield. The first season nobody talked of us winning the Champions League, but we did it.
"Now we have a much better squad and experience and I have great confidence in my team to play in big games."
