Angry Brazilian players hit out over no-sex rules

Stringent concentracao camps draw ire of frustrated teams

The Brazilian tradition of the concentracao - sequestering teams before matches and shielding them from temptations such as sex and alcohol - is under threat as players take a stand against the late payment of wages.

So far this year players at Botafogo, Portuguesa and Vasco da Gama have refused to attend the concentracao because their salaries were not paid on time.
