Offsideplus.az reports that the Serbian coach commented on the defeat: 

"It was an unlucky day for us. We had to play with losses, because I did not include Rauf Huseynli in the squad because he was not physically ready. We also had to replace Mert Celik at the beginning of the first half due to injury. In addition, we did not bring Rufat Ahmadov. We had to come up with a new player. As for the game, I have a hard time commenting on the first three goals of the opponent, because we made it possible for the Austrian national team to stand out with children's mistakes.

We pressed in the second half, although the control of the ball was equal, the players did not have the strength to fight until the end. As a result, we gave the opponent three more goals.
Nevertheless, I believe in children. They did what they could. Defeats in these two matches should not discourage the players. "
