Victor Osimhen already registered 2 goals for this season, it is a great start and the only way to crown it is by remaining consistent. Not to be sentimental with the judgement as a fellow African, Osimhen is far more better striker than 90% of players in the Premier League, what he did for Galatasaray alone during his loan times was enough work done to put him qualified. Osimhen would have made a better striker for many PL teams, in a way Napoli was part of the actual course why most deals fell and why some teams didn't approach.
I will not agree with this point of your and that is because I have seen good players in other leagues come to the premier league and at the end they could not cope, I have also seen players who are poorly performing in the premier league go to other leagues to excel, cuteness have a few from Manchester United as typical example, no doubts Victor is a very brilliant and excellent striker but eait until he gets to the premier league before giving judgment based on Premier League performances, do not credit the ability just yet when you are not sure if he will be able to deliver in such spirit in the premier league.
