On all the different manager games I play I like using and developing youth players but on Top Eleven is there any point in signing youth players?

I usually sign the free youth player and train him to help me get 2% training each day, but is there any point in spending 10+ tokens on the better youth player when he is barely good enough for my bench. Especially when I can try to sign a player 10 points higher for only 1 token. The idea of signing youth is good but I feel like I'm just wasting tokens on reserve players which isn't good because I never get any tokens back when I sell players.
