The World Cup in Russia has been spectacular but some decisions by FIFA's disciplinary court, including hefty fines for non-approved socks, have not been.
The World Cup rulings in FIFA's disciplinary court have not always been easy to comprehend.
Sweden were slugged 70,000 Swiss francs ($A95,000) for players wearing non-approved socks.
Players including skipper Andreas Granqvist and midfielder Gustav Svensson were spotted wearing Trusox underneath their official adidas socks.
Meanwhile Croatia were hit with the same penalty when a player took a non-sponsor's drink onto the field.
Yet a Russia fan's neo-Nazi banner and a Serbian World War II-era nationalist symbol waved inside venue drew only 10,000 Swiss francs ($14,000) fines, paid by their national soccer bodies which are responsible for fan misconduct at games.
Commercial rules can seem to be enforced more strictly than bad behaviour and Diego Maradona appears to enjoy a unique code of conduct of his own.
The Argentine great, a paid FIFA ambassador, used Facebook to explain away allegations of racism and offensive incidents from VIP seats, charges that have previously led to players being banned.
At times, the priorities and consistency in FIFA decisions can look a curious form of World Cup justice.
Even before the World Cup, FIFA was criticised by the anti-discrimination group Kick It Out for prioritising commercial gain over eliminating racism from the sport.
But sports law expert James Kitching says FIFA's approach makes some sense because the World Cup depends on sponsors and broadcasters paying for exclusive deals.
"A financial sanction is always heavy in a commercial case because exclusivity is something Coca Cola or Adidas pays millions of dollars for," Kitching, the former head of sports legal affairs at the Asian Football Confederation, told The Associated Press.
The hefty fines imposed on Sweden and Croatia followed repeated warnings from FIFA.
"If they are not seen to protect it (sponsor exclusivity), they put everything at risk," Kitching said.
Breaking commercial rules has netted FIFA up to 482,000 Swiss francs ($A655,000) in Russia.
A further six-figure sum must be paid by federations and players in mandatory fines for on-field conduct.
Teams due to pay 15,000 Swiss francs ($A20,000) for player ill discipline include Argentina, Colombia and Morocco.
Argentina are set to pay the highest World Cup fine for a second-straight tournament.
A 105,000 Swiss francs ($A143,000) penalty was for a range of offences by fans at the demoralising 3-0 loss against Croatia, topped by several men being filmed punching and kicking a Croatia-shirted fan in a walkway from the grandstand.
FIFA resisted calls to suspend Switzerland players Granit Xhaka and Xherdan Shaqiri.
Its rules suggested mandatory two-game bans were possible for celebrating goals with hand gestures of an Albania eagle likely to provoke rival Serbia fans. Both players were fined 10,000 Swiss francs ($A14,000).
Croatia defender Domagoj Vida was only warned on Sunday for a social media post with comments celebrating Ukraine after helping his team eliminate Russia in the quarter-finals.
Before the 2014 World Cup, FIFA banned Croatia's Josip Simunic for 10 games for leading fans in a nationalist chant after a qualification playoff.
Apparently there's no consistency, although Kitching suggests: "There has been a shift perhaps on how (FIFA) have treated such cases."
