i've maintained a fairly good side saving any tokens i get over 3 or 4 seasons,i then buy at least 3 18yrs in auctions although i havn't needed to do this for last two'seasons if you are clever you can save at the very least 700 greens over the season and using these power train your 18yrs,you can get 1 token 18 players if your canny enough as well, over the season i only train my main 11 players and use subs in friendlies to get greens etc i've won a league on average once every 3 to 4 seasons doing this,
