Buy a player on U21 will cost 15-24 token,is it worth for buying them but no do any power train on them? On the tranfer market we can find a far better player than our U21 player and we usually just need spend no more than 15 token to get them,what the point to buy a U21 player without SA? So is that U21 player just for those token buyer to buy and use power train on them to train those player till become a beast?Is it U21 not suitable for a none token buyer because we can use those token buy 2,3 player on market?
