The 18 year-old left-sided defender has broken into the Corinthians first team in recent games.
Globoesporte says United have first refusal on Dodo, which expires at the end of February. United can buy the teenager for €6 million.
Interestingly, Dodo's asking price is the same as what Corinthians sold Andre Santos to Fenerbahce for last year. Corinthians hold 70 per cent of Dodo' registration, with investors owning the remainder.
