The Croatian midfielder moved to the Bernabeu from Tottenham in a £35million deal in the summer.
But he has struggled to hold down a first-team place, starting just eight league games and scoring only once.
Modric was also voted the worst signing of the season in La Liga by readers of Spanish newspaper Marca.
And following recent criticism from boss Jose Mourinho, Modric said: “This is Real Madrid. I understand there is great pressure for new signings to succeed here.
“I’m not making excuses, I am not that kind of person, but it is very challenging to adapt to life at a big club like Madrid.
“I have had a few good performances, if not in every game, but I believe that I can prove I have something to offer.”
