I do not use negotiations because simply I do not know if the guy is fast trainer or not. I have used it once, got 18 yo MC guy and his training rate was like +80 on hard rate... that was big flop, since than , I rather wake up in the morning, get my NGE lad and train him hard since Nordeus introduced feature - you buy new player, he wont get injured , so in the same day I buy , I train SA, I give him extra star and he is ready to go ....
