The emotions were palpable in Friday night's meeting between Switzerland and Serbia (3-2).
The players argued with each other, shouted at the referee and made gestures towards the stands.
When Xherdan Shaqiri scored 1-0, he celebrated by putting his index finger to his mouth, as a silencing gesture.
A quarter of an hour later, Serbian star Dusan Vlahovic struck - and celebrated in the same way.
After the match, the Swiss defender Fabian Schär talks about the gestures and emotions.
- There are a lot of emotions.
It's hard to control yourself in matches like this.
In the end, we are the cooler team, that's why we win, he tells C More.
