So i sold my player 93 rated to some guy that maninging Barca and today se sells that same player 107 rated how is that possible ? Does he skips traning with him ,3* traning ground or what ?
I don't see any confusion here and your reason for asking this question. You sold a player to some manger who trains that player and then decides to sell the player out, So?
He could have been training the player without playing him, he probably could have fast tracked the player's training using boss coins, intense friendly event or the player may be really very young and trains fast, he may have improved his training ground to level 3 thus his players trains faster and so on.
