Born in São Gonçalo, Rio de Janeiro, Vinícius Pacheco started his career in Flamengo.
In 2008, he joined Ipatinga on loan, but only played one match in Campeonato Mineiro before he left the club in February.
On 2 July 2011, Red Star played a friendly match against SC Columbia Floridsdorf from Austria.
Pacheco broke his leg in the 40th minute of the match and was carried out of the pitch.
He will make his league debut for Red Star 9 months later, on 24 March 2012, as a substitute in a 20th round match against Borac Čačak.
