Serbian football association vice president Savo Milosevic has questioned why the video assistant referee (VAR) was not used for a penalty appeal during his team's 1-2 World Cup loss to Switzerland here.

Referee Felix Brych waved play on after Serbia striker Aleksandar Mitrovic fell to the ground while jostling with Switzerland defenders Stephan Lichtsteiner and Fabian Schaer during the second half of the match at Kaliningrad Stadium on Friday, reports Xinhua news agency. "I understand that maybe the referee didn't see it, but that's why we have VAR," Milosevic said. "What are those guys doing up there?"
