Marcelo Labarthe previously played for the rivals
Internacional and
Grêmio. He started in the youth categories of
Internacional, known only by his first name,
Marcelo. Inter's president at the time,
Fernando Carvalho, suggested the change to only
Labarthe, the surname of his
French origins, because it could be more attractive for the
European leagues, where the boy could get
dual citizenship (in a similar case of his fellows from Inter's youth team,
Rafael Sobis and
Marcos Camozzato). When he went to the main team, he used his first name along with his last one,
Marcelo Labarthe. ==Honours==
