Juve are chasing the midfielder.
Giaretta told calciomercato.com: "Can Pereyra leave? This remains to be seen. If there was an official request from Juventus, then we'd be happy to sit down and talk about Pereyra.
"We are talking about an important club and Pereyra is now ready for the big step up in his career. If Juve make this attempt to sign him, then we'll take it into consideration."
