So to lower the amount of fouls, you should sell the players with the most fouls per game and replace them with more careful players, because you can't train them to foul less.
Which sadly caused a number of potentially valuable trainees to plummet in value overnight (in the eyes of the most savvy managers)
I am disappointed this is not included in the rules as for the more casual user this is likely to be a big unknown and something that can be a costly mistake.
I hope i dont get a response saying people should check the player stats more closely because as it is rare you buy a fully complete player and I for one expected that if I place a newly purchased player in amongst better team mates and a more succesful side and train them then RB/JS % etc etc would improve.. I would also hope this would reduce their propensity to foul (through receiving better passes and coming up against worse players..
This is clearly not the case and the 'hidden' physical stat is not only a major disappointment to have to discover via the BB community and not the staff but it is IMO an uneccessary feature to implement into the game. I have traded a large number of 'foulers' since this information became common knowledge. I have even traded them as they can be bought cheaper and the transfer compare wont pick up on this. Overall I sympathise with those that have found this out the hard way and those that spend a lot of time training up someone who will always be unlikely to play out a full game for you.
