Guys, I don't really know about this. As i saw in this forum, about Mutant players, I started to train one. One with 3 stars. But after a couple of training session he is not giving any rise in %. I've already seen some threads about training and also about grey and white bar things. Honestly i didn't get it. The players grey bars are almost below 20% and whites are somewhat between 60-40%. I need a help to train my mutant.
