"It is great news that Fernando Torres has now become one of my teammates at Liverpool," said the Basque.
"There were so many rumours that he was going to come into the Premier League and I was constantly checking the news to see if we had signed him.
"He has shown over the last few years at Atletico Madrid how much quality he has got as a player. It will be a major challenge for him in England but I am convinced he will be a big success over here.
"We will help him to settle in from day one and help him adapt to the club, the city and living in England.
"With Fernando, Peter Crouch and Dirk Kuyt we are going to have one of the best attacks in Europe. It will be our task to help set them up for as many goals as possible.
"Fernando is one of the best forwards in Europe and it will be great for us to have him in the team. I believe that he is going to be a big reinforcement for Liverpool."
