Modric is into the final year of his contract at Real Madrid, but the Croatian midfielder has emphasised that he has a good relationship with the club.
"I'm too old to go back to Tottenham," Modric told FourFourTwo. "I still have a year left in Madrid and then we'll see what happens.
"I feel good and I want to continue playing football for a few more years. I am focused on Madrid and the things we can achieve this season.
"Afterwards I will sit down to talk to the management, and we will look for a suitable solution for everyone. I have forged a good relationship with all the people of the club and no matter what happens there will be no problem."
