"It is clear that this will be another good test and opportunity to see at what level we are.

PAOK striker Aleksandar Prijovi echoed the statements of Obradovic, saying the Nigerians are a physical side but it's important for Serbia to win after losing to Morocco.
He said : "Nigeria is a national team that deserves a respect, its players are physically strong and the next match will definitely be a good test for us. We will do everything to win, we will give the maximum to score better than in the previous match.
"The outcome of such matches is not primary, because it is important to correct some things. It is important for us to win."
