The same source that told me the about the return of Bonucci to Juventus on 10 July, tells me today that by 15 August Pjanic will be sold and Milinkovic Savic will arrive in his place.
His book value is ~19.2M. If sold for 100M, that is an 80M capital gain. If we're talking about 3 year periods as per FFP, that would cover ~27M annual charge for 3 years, which is the equivalent of an 133MM player on a 5 year contract. Wages would probably be equal or lower.
