Luka Modric admits he's unsure of his future at Real Madrid.

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.

The 35-year-old made clear that he is too old to return to Tottenham Hotspur, which would see him follow the same route as Gareth Bale.

"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."
