Antônio Dumas Ramalho Esteves (born November 28, 1955 in Santo André, São Paulo) is a Brazilian football manager who is currently the head coach of JS Kairouan in the Tunisian Ligue Professionnelle 1.
Dumas explained in a letter sent to a Brazilian media that he wasn't dismissed from the Togolese national team. It was he who wanted to leave, having received the job offer from the Equatoguinean Football Federation to be the coach of its national team.
Naturalization of players
Being the Togo's coach and later the Equatorial Guinea's coach, Dumas naturalized to Brazilian-born players for improve the level of both national teams, but the results weren't ideal.
Togo had six naturalized players (Hamílton, Mikimba, Bill, Fábio Oliveira, Cris and Fabinho) in 2003, who took part of the Qualifications to the 2004 African Cup of Nations and the 2006 FIFA World Cup. And Equatorial Guinea had, minimally, eight naturalized players at the request of Ruslán Obiang Nsue (Danilo, Ronan, André Neles, Daniel Martins, Léo Quirino, Fernando, Anderson and Alex) between 2005 and 2007, who took part of the 2006 CEMAC Cup and the Qualification to the 2008 African Cup of Nations.
