it depends about your target. Do you wanna keep him on your roster? Do you want to sell him soon, later?
Personally I'm not searching anymore in the TL players with potential superstar but if you wanna grow him for your "personal use" a well balance superstar could be a nice player.
If you wanna sell him for sure he doesn't worth a 4 lvl youth and probably you'll have to train him a lot to have a decent profit in the best case.
