After an unassuming three-and-a-half-year spell at RC Lens which included a loan to Ligue 2 club Stade Lavallois, he moved, in January 2002, to Spanish Segunda División team Racing de Ferrol – still on loan – helping Albacete Balompié to achieve top-flight promotion the following season.

[1] For the 2004–05 season, Delporte joined CA Osasuna, being an important attacking element in his first two years, including 27 games with three goals in the second as the Navarrese tied a best ever fourth-place in La Liga.

In 2004–05's Copa del Rey final he started against Real Betis, setting up John Aloisi for the 1–1 equaliser (eventual 2–1 loss after extra time).

[2] However, subsequently, Delporte would be severely hindered by injuries, totalling little more than 30 league appearances in four years,[3][4] none whatsoever in the 2009–10 campaign.

[7][1] On 20 December 2011, Delporte returned to active and signed a six-month deal with Angers SCO in his country's division two.
