The 24-year-old, who is expected to be a key member of the Brazil side for the 2014 World Cup, has been linked with a host of European clubs.
It has been suggested that Corinthians have emerged as the favourites to acquire his services, but he has quelled talk of a move.
He told Globo Esporte: "I don't know anything. Corinthians are a great club and I won't say I wouldn't like to play there.
@I'll arrive in Rio de Janeiro to know what's going on. But I'll keep focusing on my job."
Manchester United have previously been linked with the defender.
