Serbia and Albania are both facing the possibility of being sanctioned by Uefa after their Euro 2016 qualifier was abandoned on Tuesday night in bizarre circumstances.
Their encounter was initially halted just before half-time by a drone trailing a pro-Albania banner hovering over the the Partizan Stadium pitch. However, the incident erupted after Serbia defender Stefan Mitrović brought down the flag, which seemed to upset a number of Albanian players and a melee involving some players from both sets of teams occurred.
It forced English referee Martin Atkinson to lead the teams off the field, as disruption in the stands threatened to boil over, with objects being thrown onto the pitch at Albanian players in the wake of the chaos.

Uefa is likely to take a dim view of the controversial incident and match delegate Hari Bin confirmed the governing body will investigate what happened in Belgrade.
Quoted by Serbian media, including the popular Sportske website, he said: ''You saw what happened and at this point I cannot speculate further as to who was responsible and accountable. Uefa will take further steps on the basis of the official report.''
Albanian supporters had been banned from entering the stadium by Uefa on safety grounds and the match was set against a backdrop of tight security.
Tensions have never been far from the surface between the nations over Kosovo, the province with which both countries share a disputed border and is recognised as independent by the United States and major European Union countries but not by Serbia - a bone of contention with Albania.
