??????? ohhh shi* I have a young player that can win 10 of quality in 10 days, because he win 1 training point for every training of 20% ........thats very normal man..
2 seasons ago, I power trained a player from 112 quality to 130 quality in the space of about 4 days, It can be done if your willing to buy the tokens and spend the time to repeat training and feeding boosters over and over again.
