well, I don't agree with that. not that Khris is wrong, but he 's playing with no wingers (using 3ST or 2ST +AMC).ST's contribution, 1 goal per match aprox is OK, assistances + goals
If playing that way, of courese you expect that from your ST, but if you're playing with wingers, they're almost scoring as strikers (and in many cases more).
The latest season, I can see that the performance of STs has dropping a lot in the case you use wingers.
At that moment (in the top 5 scorers), in the three leagues of my teams, there are
in one, two ST
and in the other two leagues, only one ST. The rest are wingers or MCs.
