In this case Juventus management just need to sit down, refuse small offers, and wait who will offer the most value of transfer. Cherubini and Aribavenne have everything in their hands. Even if de ligt stays in Juventus for one year, Juventus won't lose so much because we already need good CB and we have him in de ligt and also he will have good value next year even he is in last year (in case where he won't sign a new contract).
