Real Madrid playmaker Isco offered no guarantees over his future, suggesting that he may have to leave the club.
Isco, 24, took his chance in the first-team on Saturday, setting up both goals in a 2-0 victory over Espanyol at Santiago Bernabeu.
The Spain international was linked with a surprise move to Barcelona in January, while Premier League clubs are also reportedly interested.
Goal understands Madrid have pushed back talks over Isco's contract to the end of the season and the midfielder has hinted he may have to quit if he does not get more regular first-team football.
"I'm calm. What worries me is to have minutes," he told beIN Sports. "A player's career is small.
"I'm happy here and would stay many more years.
"From now until the end of the season, we will make a decision. It is my future at stake."
Isco has made just 11 league starts this campaign, while he has featured in the Champions League only once.
