A manager buy a player during an auction, in my opinion, overpriced. Out of curiosity, I go to see his team. At first I see he is at lv. 48 and the first question arises spontaneously: how is it possible that a so high lv manager can do the auction with noob people like me?
Let's go ahead, I open his team screen and see that he is probably rebuilding it. Nothing strange so far until you see that the player he just bought has risen from the level 48 to lv 258

How is it possible?
