SA, Skillpoint or Scout?

[k1tb]

Hi!
I want to hear suggestions about one thing.
Which is the most effective ( the best ) way to make your team stronger?
Buy a scout? ( 69T and 105M )
Train a fast trainer ( He gains about 120+ with hard training "old version" ) Fast trainers are J.Ask (ST), H.Hallik (DMC) and A.Prieto (DR).
Making SA, using green packs...
Training the best goal scorer in team ( 30 games, 50 goals ) , but he is 5* and gains 40+ per hard training.
Or wait for recommended players?

All the suggestions are welcome and maybe you have more ideas how to spend tokens the best way...

Picture about my team:
