The Argentine admits he treasures his time in Spain.
He told Marca: "Yes, there are some who miss me and others who do not, but that's football ... Madrid gave me the possibility to reach the top, to be big, to be among the top eleven players of the world that year.
"It has given me everything and it is obvious that I will be eternally grateful.
"My best memory? The Champions League, of course, but my first Copa del Rey too, because I gave the pass for the goal, and then all the friends I left there and I still have contact with them. And that's important because after football you have life."
