Around an hour into the match, Arsenal midfielder Xhaka angered the Serbian bench after appearing to grab his crotch in their direction.
The gesture prompted several Serbian players to run onto the pitch and confront Xhaka, who was booked by the referee.
After full-time, Xhaka was involved in another controversial moment after he was seen wearing a shirt with the name 'Jashari' on the back.
Asked afterwards what it meant, Xhaka claimed there was no "political background to it whatsoever" - stating it was for his Switzerland teammate Ardon Jashari.
However, it is also the surname of Adem Jashari - a founder of the Kosovo Liberation Army, a Kosovo Albanian separatist group that fought for independence from the former Yugoslavia.
Xhaka and his Swiss teammate Shaqiri are both of ethnic Albanian heritage linked to Kosovo, which declared independence from Serbia in 2008.
It is the not the first time Xhaka has been involved in a controversial incident against Serbia.
Both he and Shaqiri were fined by FIFA in 2018 for make an eagle gesture, associated with Albania, after scoring against Serbia at the World Cup in Russia.
Xhaka potentially facing FIFA investigation
PA, as reported by the Daily Express, have indicated that Xhaka could now be the subject of a FIFA investigation over his latest gesture.
Switzerland boss Murat Yakin said he will "wait and see" if action is taken against Xhaka.
"We will enjoy this moment, it cost us a lot of emotions and energy. It was a fair match," he said.
"Before the game a lot of people were talking about the situation but we were able to face that challenge.
"We are happy we are moving on. Everything else is speculation and we will wait and see."
