The Serbian Football Association has said it will make a formal complaint to FIFA after Switzerland’s Granit Xhaka and Xherdan Shaqiri celebrated their goals during a 2-1 World Cup win over Serbia in Kaliningrad by performing an Albanian nationalist symbol, as reported by The Guardian.

Xhaka and Shaqiri, who are of Albanian-Kosovan heritage but were raised in Switzerland, put their hands together to form what looked like a double-headed eagle similar to the one on the Albanian flag.

The gestures risked inflaming political tensions in the Balkans among Serbian nationalists and ethnic Albanians. Kosovo is a former Serbian province that declared independence in 2008. Serbia does not recognise Kosovo’s independence and relations between the two countries remain tense.

This is hard to take politics away from football, but probably the guys from Switzerland should not provoke their opponents. On the other hand, Serbian are not to pay attention to such provocations.
