Javier Hernandez has told Real Madrid that he does not want a permanent switch to the Bernabeu if they cannot guarantee him regular football.
The 26-year-old has struggled for first-team opportunities for much of his season-long loan from Manchester United, starting just nine games in all competitions.
An injury to first-choice striker Karim Benzema has seen the Mexican thrive in recent weeks, netting four in his last six games.
However, Hernandez warns coach Carlo Ancelotti not to avail of the chance to sign him permanently unless he intends to use him more often next term.
"The season has been very complicated," the attacker told beIN Sport. "But, in football, sometimes the wheel turns very quickly. And thank God, I now have more possibilities to play.
"My parents taught me that patience and perseverance are part of learning. Today, I feel very good. For many people, I was already finished here, but it was only the beginning. One must not lower one's head.
"I learn every day in this great club and all I am grateful to God for that. I know that at Real Madrid the competition is strong and the minutes are rare and my intention was never to complain. But, at times, I just expressed the frustration I felt. As I am not one to be content with sitting on the bench, I always want more."
It was reported last week that Los Blancos do not intend to sign Hernandez on a permanent basis after their deadline to make a formal bid passed without acting.
