i save 50 skill to either give new position or ability but i get say a player with a player with ability from transfer market e,g a defender that`s dc with heading ability then i can use saved skill for blocking ability, i won`t train player till i know if i need this ability so i will havel no control on how i can train player, even in real life it take time to train player`s, Look at Steven Gerrard he started as DR when he made his debut for Liverpool he did not suddenly become one of best midfield player`s over night, NO it took time and training
