The flashpoints had been well signposted. When Serbia and Switzerland met in Kaliningrad at Russia 2018 it was clear from the outset that nobody would be fading out quietly. Xherdan Shaqiri’s decision to recognise the land of his birth with a Kosovo flag stitched into the heel of his right boot had warmed a tinderbox that was already well stocked and, when Granit Xhaka celebrated his thudding equaliser by forming an Albanian eagle with his hands, tensions ignited.
Both players repeated the gesture when Shaqiri scored a dramatic late winner that ultimately ensured their side were the ones who reached the last 16; the recriminations were long, loud and ended with Fifa issuing several fines.
