I would never scout STs. I don't buy tokens anymore, but when I did I learned to never make that mistake. I suggest to only scout midfielders as they are the only consistently good performing players in my experience. DCs, GKs, and STs have always never really "wowed" me in overall performance over their entire career. DLs, DRs, AMLs, AMRs, and AMCs/MCs on the other hand go on to break records for my club.
The worst scout purchase, ironically, was this ST that through his entire career from 22-28 (i had to sell that bastard) scored 17 goals in all competitions, starting every game since purchase. Without my AMLs and AMRs (bought in auction btw) to carry him throughout his career I would have spent money to essentially decrease my winning potential. Do not buy STs lol
