Assuming this is true, it's a stunning lack of ambition any way you look at it.
He turns 22 in a month. He's not an 18 year old anymore.
Players like Pogba and Coman come to Juve at 18 refusing to be loaned out, and fighting for every minute they can get on the pitch. COman wanted more minutes so we sold him to Bayern, where he's fought for minutes at another top club. Dybala came to Juve as a 21 year old last year. Didn't refuse a move saying he wanted to stay at Palermo. Rugani didn't insist on remaining at Empoli, instead he came to fight for playing time in a stacked line up of CBs, competing with the 3 best CBs in Italy. Even Zaza came here knowing he'd have to fight tooth and nail for every minute on the pitch.
To say the very least, Berardi's lack of ambition and drive to play at a top club and be one of the best in the world is lamentable.
