Lawyer Marco Polo Del Nero took office Thursday as president of the Brazilian Football Confederation (CBF), with the promise of modernizing the country's most popular sport, according to dpa. "Progress, modernization, legality. Stimulating responsible management in clubs. A search for governance models. Openness, legal security. Awareness of [football's] social role. That is what the new Brazilian football will be like," said Del Nero. The 74-year-old lawyer is set to replace Jose Maria Marin at the head of the CBF, although Marin will stay on as his deputy. The men received an enthusiastic reception at the handover ceremony at the CBF headquarters in Rio de Janeiro, although Marin - who replaced the powerful Ricardo Teixeira in March 2012 amid corruption allegations against Teixeira - will probably be remembered mainly as the man who presided over the worst thrashing in Brazilian football history, 7-1 against Germany, at home in Belo Horizonte, in the semifinals of the 2014 World Cup.
