Senegal's coach Aliou Cisse's celebration when his team scored the winning goal against Poland in their World Cup opening game has become an internet sensation.
Senegal will take on Colombia next but those obsessed with cleanliness probably can't wait until their final group game against Japan where both teams will be looking to out polite each other in the stands.
The search for the World Cup's most polite fans is down to two finalists: Japan and Senegal.
Japanese and Senegalese supporters received praise after they were seen picking up their trash and tidying up their stadium section following their respective matches Tuesday.
"It's not just part of the football culture but part of Japanese culture ..."
"You often hear people say that football is a reflection of culture. An important aspect of Japanese society is making sure that everything is absolutely clean and that's the case in all sporting events and certainly also in football".
Japan coach Akira Nishino talked before the match of his worry about the "psychological impact" of Monday's quake which hit the Japanese city of Osaka during morning rush hour, killing at least five people. It is a habit drilled into citizens from a young age, with students expected to clean their school classrooms and hallways.
"Senegal achieved a historic triumph", Argentinian media outlet TyC Sports tweeted.
Not only did these teams impress World Cup viewers - their fans did, too.
The result leaves the African nation, famous winners over defending champions France in the opening match of their last World Cup appearance in 2002, level with Japan who beat Colombia 2-1 at Mordovia Arena. The Lions of Teranga's next match is against Japan on 24 June.
