Lopez came through the system at Real.
"I am really excited and very happy. Itâ€™s all been so quick. Iâ€™ll have to get used to it. To go back to my club, the club I love, where I grew up and got trained is beautiful and something really special. Iâ€™m going to make the most of this opportunity Iâ€™ve been given and thank all those that have made this signing possible," he said.
"I found out from the media that Real Madrid were looking for a goalkeeper and I was in the running. Yesterday my agent told me that he was in Seville with Del Nido, looking at the possibility of a happy ending. By the end of the day it was all confirmed and you can imagine the rest. Hours with no sleep, having to say goodbye to mates in Seville, travel up and be here. I donâ€™t have any other words other than those of gratitude and excitement."
