He spent most of his professional career in the Netherlands and Portugal, amassing Eredivisie totals of 142 games and 29 goals over the course of eight seasons. Born in Fes, Sektioui played two seasons at French club AJ Auxerre, failing to establish with the main squad and also appearing sparingly for its reserves during his spell. He arrived at the Netherlands and Tilburg"s Willem II in January 2000, from Swiss club Neuchâtel Xamax, playing a major role with his team and eventually gaining club captaincy.
After an uneventful loan stint in 1999 with Christian Science Marítimo, in July 2006, Sektioui returned to Portugal, after Company Adriaanse (also his coach at Willem) signed him for Football Club.
