Ok now I am starting to get it ) Before , I was thinking that every player between age 18-22 (regardless value) trains extremely fast . But now I see that this is not the case . I bought 18 year old ST with 23 quality and now I see that he trains very very slow . In contrast another 18 year old MC with 1.75 million value trains very fast (gets about + 125 gain every match ). I have to keep him in team for long then ?what will happen to him in next season ? I also don't get ths stuff with gaining or losing stars ...I only want to build a long term young squad with good quality ..
