Real Madrid playmaker Isco has indicated that he could leave unless he gets more playing time but said he still aims to be a success at the club.
Isco, who joined from Malaga for €30 million in 2013 and has won two Champions League medals, has rarely been a regular first choice.
He was whistled by fans at the Bernabeu before being substituted in Sunday's home draw with Eibar.
And in an interview with Marca, he said he might need to move to a new club. "I have been two months, practically, without playing," he said. "It's difficult when you're training well and the boss does not put you in.
"But in the end it's my own fault. In the end it is me who is responsible. I want to see where I can improve to get in there.
"I am not going to give in easily. I know I will be a success. I don't know if that will be with Madrid -- I hope so. But if not, I will be a success somewhere else."
The 24-year-old has been linked with a move in recent months, with Tottenham, Manchester United, Arsenal and AC Milan reported to be monitoring his situation.
"I have two years left on my contract at Madrid," he said. "The club said nothing to me, and I didn't do anything to look for a move.
"They've not called me either to renew it, so I am relaxed. I look at the day-to-day, which is the important thing."
Coach Zinedine Zidane had warned Isco in preseason that he would not be a first choice in this campaign.
But he said: "I want to train hard, to show that I can be a starter. He [Zidane] told me it depended on my performances.
"There is a lot of competition and a team shape which is practically set in stone. It's possible that, at another team, I would play more."
Isco added that he had talked about the situation with teammate James Rodriguez, who is in a similar position.
"The important thing is that the boss makes the decisions," he said.
"If he thinks it's better for us not to play, we cannot do anything else other than train and pressure him that way."
