Xherdan Shaqiri's last minute victor capped an impressive comeback for the Swiss in Kaliningrad on Friday after Granit Xhaka levelled following Aleksandar Mitrovic's opener.
Shaqiri was born in Kosovo before it declared independence in 2008, something Serbia fails to recognise.
I think we all together need to steer away from politics in football and we should focus on this sport as a attractive game and something that brings people together.
"I think we should not talk that much but show our mettle on the pitch".
Unsurprisingly, jeers greeted his every touch throughout the match and, for a while Serbia looked good value to secure their first progression to the World Cup knockout phase since becoming an independent nation, their opponents struggling to repeat their heroics against Brazil.
Federation Internationale de Football Association must also make clear that controversial political statements must stay far away from the pitch during the duration of the World Cup. You can see what I did, I have emotions.
Xhaka silenced the Serbian contingent in the 52nd minute, however, when he rifled home a loose ball in spectacular style from 25 metres before Shaqiri ran onto a through ball and finished with aplomb to win the game at the death.
Shaqiri even had a Kosovo flag stitched into his boots and was booed by the Serbian fans when his name was read out prior to kick-off, per BBC.
The Serbs had taken the lead through a fifth-minute header from Aleksandar Mitrovic, before Switzerland struck back with a fierce drive from Xhaka on 57 minutes, before Shaqiri burst free from the half-way line to score in the last minute. Switzerland, however, made a brilliant comeback and with the win, became the first team to come from behind and win the game at the 2018 FIFA World Cup.
Die Nati nearly leveled matters on the half-hour mark.
Shaqiri latched on to a pass in his own half with Serbia's players pushed up and carried the ball forward before slotting it past Vladimir Stojkovic.
Switzerland grew in stature after the break and were rewarded with a spectacular equaliser courtesy of Xhaka's left foot.
Coach Vladimir Petkovic brought on attackers Breel Embolo and Mario Gavranovic in a bid to force a victor, and Gavranovic forced a smart save from Stojkovic from a close range effort with 10 minutes remaining.
Switzerland kept Serbia under pressure for the remainder of the game, and Xherdan Shaqiri broke through with the game-winner in the 90th minute.
Mario Gavranovic, Josip Drmic and youngster Breel Embolo proved highly effective second-half substitutes who exposed a visibly tiring back line.
