Juventus are prepared to listen offers for Paulo Dybala at the end of the season.
The Argentina international has become unsettled at Juve amid tension with coach Max Allegri this season.
Corriere dello Sport says Real Madrid and Manchester United are watching developments closely and been encouraged in their interest by Juve intermediaries.
The Bianconeri feel now is the time to cash in on Dybala - and will seek at least €100m to sell.
The board will also encourage Allegri to select Dybala to the end of the season so to maintain his price.
