Chelsea are reportedly stunned by Victor Osimhen's demands ahead of his potential transfer from Napoli.
The two clubs have been in talks over the Nigeria international in recent weeks.
However, the deal could collapse due to the striker's £500,000-a-week demands, as per The Sun.
Osimhen will become the highest paid player in the Premier League if his demands are met by the Blues.
Chelsea and Napoli are yet to agree on a fee for the Nigerian star, with the English giants reluctant to pay his €130m buyout clause.
They have also seen their proposal to get the 25-year-old on loan rejected by Napoli.
