The 25-year-old Senegalese forward became the Toffees' third-most expensive signing ever after completing his move from Lokomotiv Moscow on deadline day but he says his valuation does not at all bother him.
Niasse, who previously in Turkey with Akihisar Belediyespor, is confident he will be able to justify his price tag, telling Sky Sports News HQ: "I don't have any problem with the price tag.
"Everywhere I have been it has been the same. When I went to Russia from Turkey after only one season they said that they had paid a lot. For one and a half seasons I showed them I was worth it."
