He told the Mirror: "Liverpool are one of the biggest clubs in the world and I am going there to take an important step in my career, not to be a replacement for anyone.
"I think it is time for me to take the next step in my career and Liverpool can help me do that. I have confidence in my ability to move forward and to grow as a player.
"I described the move as emotional for me because it is such a big club and it means I've reached another level.
"But I am calm because I feel I am ready. I want to show that I am capable of playing at the level of this huge club.
"I am excited to be going to England. I want to play in the Premier League. And I hope I will be helped to settle there by all the Spanish speakers at the club, including Luis Suarez."
