The 23-year-old never considered leaving Madrid in an effort to get more first-team football.
"I never thought about it even in the difficult times," he said.
"That is my strength and my philosophy. I realise that when one is lucky enough to be at such an important club as Real Madrid you should be prepared for suffering. It is part of the game.
"It's easy (to explain my good form). The coach gave me confidence and enabled me to string together several performances.
"Mourinho again put me in the side and that changed everything. I came to Madrid to score goals and provide a great spectacle of football. I want to please people. In Madrid I do what I did in Lyon, but better!"
