Gremio want to tempt Liverpool midfielder Lucas Leiva back to Brazil.
The Daily Mail says the 27-year-old is in and out of Brendan Rodgers' side at the moment and the Brazilian club sense he could be open to a return home.
Lucas, however, has made it clear he would prefer to stay at Anfield if he has a fair chance of contributing.
Napoli have been linked consistently also but Rafa Benitez is struggling to get the financial support he wants to push the Italian club forward.
