The former Liverpool defender has big ambitions for Los Che.
He told AS: "That Real Madrid and Barcelona have a different budget is a reality, it is something obvious and objective, but if football is anything it is irrational. This is why we are so passionate about it.
"Not all teams are made from a base of money and we are going to compete with Real Madrid and Barca."
"I am very happy to be here. It excited me when I arrived. I remembered the moments I lived here as a player, but now is a new era. We are happy and I am sure that with our work we can form an important team."
