The former Manchester United striker has fallen down the pecking order at Real, following the arrival of Cristiano Ronaldo, Kaka and Karim Benzema this summer.
He said: “The easiest thing for me to have done would have been to leave for a lesser team. But I’m not going to leave Real Madrid.
“I want to know what I’m capable of. There are still a lot of options when it comes to playing.”
He added: “I know I can play at the highest level.
“Physically, I feel better than before the injury. I only need to find my rhythm and that will come with matches.
“The doctor who operated on me said that I could play three more years and then when I retire from football I won’t have any problems.
“Before the injury I didn’t feel good. I lost three years.”
