Talent feeds into potential, but that's not the same as correlation because sometimes talented players end up not realising their potential. And you may not have specifically said that talent equates simply to potential, but you've strongly implied it in everything you've said.
I haven't dismissed the talent aspect concerning any player (whether Kane, Martial or whoever), I've simply said that talent is only one factor in potential. And in any case, Kane clearly has plenty of talent.
You don't seem to understand the actual meaning of a fair few words involve in this conversation - and hence you see contradictions where none exist.
I don't see that Pogba has more potential than Alli, because Alli has done more and shown more than did Pogba at the same age. And Martial has yet to prove he's more talented than Kane, especially considering that Kane's talent centres mostly on goal-scoring and in the current calendar year he's scored more league goals than any other striker in the Prem bar none.
