The 19-year-old centre-back, who has made a big impression since his arrival from Fiorentina in August, is unfazed by the prospect of playing five games in the space of 15 days.
"To me it is not a problem," said the Serbia international. "I am always happy when I am playing, so this time of the season makes me happiest of all!
"My father and mother are here, so I won't miss my family.
"I don't look at the two long away trips as a problem at all.
"Now we concentrate on the Sunderland game, and then we focus on Norwich - it's not a headache.
"The league in Italy stops, and we have a break, but playing here is no problem for me. I am looking forward to the next couple of games."
