As far as I can tell, those managers that have led their NT to the ultimate glory get no recognition in GKO. Looking at my friend Aizen's profile nowhere can I find that he achieved this feat...probably the first and last time the USA wins a WC in any universe or reality.
Personally I think
a WC trophy should be added to the achievements page...or at least to the manager page.
Also I think
managers who win either the WC or WCL should get a tiny trophy by their name in chat 
anyway it's not a top game priority, but something small that should be added whenever it is convenient
