well yes, AMC could also play some critical role like Modric (maybe like a MC with forth arrow).
I use some times AMC but he is not so steady in performance like the wingers.
But I 've never seen a ST in a formation with wingers to be a legend.
Of course if he has high quality and you put him for f-k and penalties, he 'll score a lot.
Or if you 're scoring a lot of goals, he will get 1-2 per game.
But that's another story.
