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.
Why won't he perform very well, if we are comparing strikers, Haaland and Osimhen will go into same category, i think both have identical pattern of finishing, if Haaland can survive the Premier League, i believe Osimhen isn't different not to adapt and perform well.
What about Jackson for Chelsea, Osimhen has better finishing compared to Jackson, with all the chances not converted by Jackson, most of them would have been converted by Osimhen, also including that Osimhen header is as good as his feets makes him a threat in front of a goal post, Osimhen has the individual potential as a finisher.
