"[I would also like to thank] former managers Bilic and Stimac for everything they have done for the national team and me personally, for all of my teammates with whom I have fought for Croatia's victories, and to the entire Croatian public.
"I will always remember my international career, our national team remains at a special place in my heart. I wish Croatia a successful future, starting at the European Championships 2016."
