Real Madrid midfielder Isco cannot guarantee staying beyond the end of this season.
Isco struck twice in victory at Sporting Gijon on Saturday.
"I have always made it clear that I want to be here for many years," the Spaniard stated post-game.
"I don't know why it surprises people that I want to play more.
"I want to stay in Madrid and for many years, both the club and I are going to make the right decision."
However, Isco stopped short of criticising coach Zinedine Zidane for any lack of game time.
"Substitute? Zidane creates the line-ups and is taking the squad in an extraordinary direction," he continued.
"[The win] is a sign that he is doing things very well.
"I know that I am at the best team in the world and I try to do my job with a lot of personality."
