[1] Sinval began his career in Ponte Preta, but was scouted during a youth tournament in Qatar.
He moved to Switzerland as a part of a "Brazilian invasion" of the country's football scene.
El Periódico Extremadura called him "one of the most charismatic players in the club's history".
He was not wanted by Servette at the time, and a trial with FC Wil and talks with Racing Ferrol did not come to fruition, with Sinval ultimately being signed by Étoile Carouge in the Swiss second tier.
The club contested the 2005–06 Segunda División B, and his playing was contingent on obtaining an Italian passport.
