I always look at what the senior players determination and influence is, as if its less then 15 out of 20 then i wont use them to tutor my youngsters.
Include this with their personalities and position recipe for success for me normally.
Cleverly is a good shout versatile and I landed him in the second season for 8.5mil but well worth it and Jason Lowe can play many positions including RB I got him for 4.3mil.
You need a scout with a decent judging of potential ability and get him to scout preferably the country he is from as they will have good knowledge and they report back every month or so the more scouts and better there stats the better regens they will come back with. I always look for judging...
