Leicester City are in negotiations with Gremio to sign Brazilian forward Luan, according to ESPN Brazil.
The Premier League champions have sent an official to Porto Alegre to hold talks with the Brazilian side, in the hope of agreeing on a €25 million (£20.8m) deal.
Gremio are willing to part with the striker's services, but have made it very clear they will reject any bid below their €25m valuation.
Luan has scored five goals in 17 appearances this year and will represent Brazil at the Olympic Games in Rio this summer.
