The problem is, that this guys are "cheater". They can't get teams like that at normal ways. I know that on my own, because I've many Fast Trainer in my team and at 140% (8*) they don't gain that much. I trained my best two guys from last season (both 19 y.o.) at the beginning of the season to 135%. They reached 140% on 4th the of the season. Now... one of them is 145%, the other one is 142%. They played ALL games and they got around 2-3 trainings per day. If you are good at math, you know, how much money they have to spend for such a team.
You can report them, but it's useless. Since the start of Associsations, you can see them in high numbers, but Nordeus does nothing against them. I also got the answer, that they are legal, they spend money,...


And by the meaning of cheating, they use(d) VPN to farm greenpacks like hell. VPN is illegal (terms of use).
There also was a post at this forum, that they use it.
