Mateus was born in Luanda. After started playing professionally for modest Portuguese teams (he had a stint with Sporting CP, but never moved past their reserves), he signed in January 2006 with Gil Vicente F.C. of the Primeira Liga. He scored in his debut on 5 February, in a 5–0 home win against Vitória de Setúbal.
However, Mateus was at the centre of a judicial controversy that erupted in Portuguese football, known as Caso Mateus (Mateus Affair), after a supposedly illegal registration by the Barcelos club. Following a lengthy judicial battle between Gil and C.F. Os Belenenses, the former were relegated.
After an uneventful season with Gil Vicente in the second division, greatly delayed by the legal consequences, Mateus joined Boavista F.C. for the 2007–08 campaign. His new team was also eventually relegated, due to irregularities.
In 2008–09, Mateus moved to Madeira's C.D. Nacional, being an important attacking element – whether as starter or from the bench – as they eventually qualified for the UEFA Europa League. He continued to be regularly played for the better part of the following years, notably netting nine goals in 24 matches in the 2011–12 season.
He also added three substitute appearances in the 2008 Africa Cup of Nations, as the Palancas Negras reached the quarter-finals.
