Isco says he did not think about leaving Real Madrid in the summer.
The 24-year-old was linked with a move away from the Bernabeu due to a lack of playing time.
However, asked by Marca whether he considered leaving, he said: “Not really, I have two years left on my Real contract, the club said nothing and I never looked for anything to leave.”
“In the end, if I’m not the star man with (Carlo) Ancelotti, (Rafa) Benitez or Zidane, I will not be foolish and look for problems where there are none,” he said. “In the end, I’m responsible and that’s where I must improve.
“There are ups and downs and I won’t give up, I fight to the end and want to prove that I’m fit for Madrid.
“We are talking about the best players in the world, there is much competition and a line-up that is practically non-negotiable.
“I know it’s very difficult because of the competition, but I won’t give up. I work every day to demonstrate my abilities.”
Questioned about a possible renewal, he added: “I don’t know, the truth is that I have not yet thought about it, nor have they asked me to renew, so I am calm. I take it day by day, which is important.”
