Regarding good youngsters, I once in fm 10 had a season with blackburn, and after the first season or so injuries and a crap cm on forms require you to as I say do a 'macheda' where out of almost nowhere u put a on form U18 regardless of potential into the squad if that be subs, or first team, with me potts turned out to be a revelation and perform solidly and with high quality for a youngster and when I checked his potential it was something like 140 and he was always near the top of that for the couple of seasons I had with him at blacburn.
p.s I wouldn't introduce youngster on vital games though, its abit stupid doing that
