Agreed it is not clear. The OP does seem to indicate Oscar creates the list and then other people work on it, but I presume it is the other way round, with Oscar having the possibility of highlighting anyone he is particularly interested in.
I am sure that, if Oscar chose to indicate that he was a particular admirer of a certain player, and would dearly like him at the AMEX, that the wheels would be set in motion at least to enquire about said player. I would imagine Oscar would even be asked if there was anybody who had caught his eye.
