"Domestic titles are very important but to win the Champions League you are saying we are the best team in Europe," said the striker.
"This club has a great record in the European Cup but now I want to be a part of that history.
"Winning the European Championship was a great thing for me and I understood what it was to win a major trophy and what I had been missing.
"On the way home from the European Championship I made a promise that I wanted more of this success with Liverpool and it does not come any bigger than the European Cup."
