Well you can make him a SF so he'll basically need to train all skills. Which skills to train first and how long depends on preference. I like my trainees to be able to defend and pass first, so they're not a liability. Defense also trains slowly so it's a pain to do at later ages. However, something is to say for training 1v1 first in order to get in many pops for the elastic effect.
As long as you keep getting him 48 minutes a week and don't train one or a few skills endlessly, I think you'll be fine with this guy :)
