Ramos replaced Bernd Schuster as Real Madrid coach on Tuesday.
“I would like to thank the club the faith that they have placed in me. I am very excited about the prospect of coaching Real Madrid,” Ramos said to reporters.
“It is every coach’s dream and I do not want to let anyone down in their choice and hope to bring success to the club.
“The speed of the agreement has surprised me. I was invited to have breakfast with the directors this morning and we talked about a deal then and it was all signed then.
“In most of my previous jobs I have had short contracts and I will be here until the end of the season. It was a quick agreement and if both sides are happy then we can sit down in the summer and maybe extend the agreement.”
