It doesent say we would get him for 20M, only that Lotito values him that much (a fair price for such player definitely) and proposed a Berardi 2 year loan as part of the exchange, which means probably around 12-15M + Berardi 2 years loan for Biglia. I wouldn't do it personally but can see the logic behind such a move as we need a reliable 4th CM and there aren't many good ones on the market and he can replace Marchisio for the time hes injured. Hope thats not true and we get Gomes instead. If Allegri doesent want Berardi, which I doubt, we can loan him to them without taking Biglia
