Cury facilitated the transfer of Neymar to the Nou Camp from Santos, and the report in Spanish newspaper AS claims that the South American-based Barca representative has now started progressing the Luiz deal.
Barcelona are desperate to bring in another centre-back this summer, and while they've been linked with the likes of Valencia's Jeremy Mathieu and Porto's Eliaquim Mangala, the priority remains Luiz.
The Brazilian international's agent, Giuliano Bertolucci, will reportedly work with Cury on the transfer.
The two have worked together before - they were behind deals to bring Thiago Motta to Barcelona and Deco to Porto.
He even provided a detailed report on Oscar, who later made the move to Chelsea, to Rosell.
But Jose Mourinho could be the biggest stumbling block to Barcelona's hopes of landing Luiz.
While reports have claimed the former-Real Madrid boss doesn't completely trust Luiz at centre-back, Mourinho's sour relationship with the Nou Camp club could scupper their hopes of an agreement.
That, allied with Luiz's usefulness in a defensive midfield role and his popularity among the Chelsea fans, presents a significant challenge for the La Liga champions.
