Promising players are qualiy. I have two in my team for extreme master league and they are both wicked. I have a winger that has 99 accelaration, speed and ball speed aswell as a wicked cross and a unstopable shot.
I also have a new striker i am reacently ungraging. He is almost top on all the accelaration, speed, ball speed around 99 98 or 97. He has a shot ac or 98 shot power of 99 and shot tech of 95 or 98. His passing is average like alot of strikers but who needs to pass when he can score like that.
