The former Rayo Vallecano striker was unveiled to the local media yesterday.
"It's a dream to play in a great team with great quality.
"It is a dream come true. For a boy of 20 years, this has happened to me very fast: the debut, goals, and move to a big team.
"I come eager to learn and to win. I'm very young and I will bring a lot to the club."
He added: "I do not think about the pressure. I'm very young and I will learn a lot at this club."
