The striker has not participated in pre-season friendlies because he was promised the opportunity to leave if the right offer came along.
Multiple sources today reported that Simeone had agreed a transfer to Napoli, on loan for €3m with an option to buy for a further €12m.
However, now Sky Sport Italia claim that Juventus are getting ready to intercept the negotiations with their own offer.
Argentina international Simeone scored 17 goals and provided six assists in 35 Serie A games last season for Hellas Verona.
Monza and Borussia Dortmund had also shown an interest in Simeone, who wants to step up from Verona to play in the Champions League.
