Okdiario says an approach has already been made and Barca are open to doing business.
Griezmann is in his second season at the Nou Camp since his €120m move from Atletico. For the most part, there's a general consensus inside Barca that the deal hasn't worked out.
Knowing Atletico are open to re-signing the France international, a swap has been proposed by Barca, though their first offer involving Marcos Llorente moving in the opposite direction has been rejected by Atletico.
The LaLiga leaders regard midfielder Llorente as an untouchable.
Instead, Atletico have put on the table Joao Felix, while teammates Jose Giménez, Yann Carrasco and Saúl Niguez are also options being put forward.
Atletico coach Diego Simeone fully supports the prospect of working again with Griezmann and would be happy to pair him with Luis Suarez next season.
