Spain and Chile set the wrong kind of example on Fifa's fair play day after a mass brawl marred Spain's 3-2 friendly win in Switzerland.
Tempers flared after Spain were awarded an injury-time penalty with the score tied at 2-2.
A huge fight then erupted involving almost all of the players, with both benches joining in.
Both coaches shrugged aside the incident but Fifa are hardly likely to be pleased at its timing.
Television replays suggested the penalty that resulted in substitute Cesc Fabregas's late winner should not have been awarded.
"It was nothing," said Spain coach Vicente del Bosque. "We've seen an excellent game of football and these things can happen in the heat of the moment."
Chile coach Claudio Borghi was also reluctant to talk about the incident, in which nearly all the players pushed, shoved and aimed kicks at each other.
"The end was bad for both teams," he said.
Fifa president Sepp Blatter said on Thursday that he wanted the international matches played on Friday, as well as next Tuesday, to set a good example as part of Fifa's fair play campaign.
"I appeal to all players, officials and fans to set a good example of fair play, whether it be at grassroots level or at the pinnacle of international football," said Blatter.
"Together we have to take responsibility and play our part in showing fairness, impartiality and solidarity."
Spain midfielder Andres Iniesta told reporters: "You have to ask them what happened. The game was getting a bit heated and sometimes it happens, but it ends there."
Chile led 2-0 after 20 minutes but Spain came back to win thanks to two goals from substitute Cesc Fabregas, including the controversial injury-time winner, and one from Andres Iniesta.
