KALININGRAD, Russia — Albania’s national flag was at the center of Switzerland’s 2-1 victory over Serbia on Friday at the World Cup.

Granit Xhaka and Xherdan Shaqiri celebrated their goals by making a nationalist symbol of their ethnic Albanian heritage.

Both players put their open hands together with their thumbs locked and fingers outstretched to make what looks like the double-headed eagle displayed on Albania’s flag. The thumbs represent the heads of the two eagles, while the fingers look like the feathers.

In the tournament’s first come-from-behind victory, Xhaka made it 1-1 in the 52nd minute with a powerful shot through a crowded penalty area. Shaqiri added the other in injury time after running past the Serbian defense.

Their celebrations were emotional and could overshadow Switzerland’s victory.
