Well dont know. Mbaye Niang is 19 and has reach his full potential. that realy unrealistic imo. So the question still stands. Can he even develop more?
When player reaches his PA he won't be able to develop more(except mental attributes,I think).If player reaches his PA in young age he will decline as footballer sooner because he burns out.
Having the same problem with Akos Kecskes. he is 20, according to FMEL he is 143/143, but ingame i see 2stars/4,5stars. Who's lying and who's telling the truth?
