Sport Mediaset says Florentino has already made an opening bid for the Argentina international. With both clubs dumped out of the Champions League, they're free to negotiate terms for Dybala.
The offer is worth a value of €100m, with a significant cash component plus a choice of Isco or Toni Kroos. Isco is rated at €50m, while Kroos' price is €60m.
Juve have received the offer and are currently considering their options.
Interestingly, new coach Andrea Pirlo has spoken in the past of his admiration for Isco.
