The midfielder is waiting to open new contract talks.
"I arrived in Italy after just two seasons in Serbia, where the football is less tactical. Now I know better how to play here and Vincenzo Montella believes in me, so gave me confidence.
"I have also changed in terms of mentality. Before when I didn't play, I would often train half-heartedly, but now I always give 100 per cent. I would like to renew my contract with Fiorentina, but we'll talk about it at the end of the season."
