Dunga cracks whip on Brazil

Sao Paulo - Brazil players are being told not to wear hats, earrings or flip-flops while serving the national team under the command of coach Dunga.

They also can't use mobile phones or tablets at certain times, and are discouraged from engaging in religious or political discussions.

The internal code of conduct was published Thursday by the Folha de S. Paulo newspaper, Brazil's largest daily.

The Brazilian football confederation confirmed its existence during a news conference in which Dunga announced the squad for friendlies against Turkey and Austria in November.

The confederation's guide for good behavior already existed but was revised after Dunga took over following Brazil's disappointing performance at the home World Cup this year.

Dunga says the code of conduct is needed to "maintain good harmony" in the national team.
