Newcastle are understood to be interested in signing the 28-year-old as speculation surrounds the future of Alexander Isak.
According to The Standard, Brentford have made a potential deal harder by increasing their asking price from £50 million to £60 million.
The report adds that Brentford are increasingly unwilling to sell Wissa due to fears they would not be able to sign an adequate replacement.
Eddie Howe’s side have been weighing up a £35 million bid for the striker and are unwilling to match Brentford’s price tag.
Wissa is seemingly pushing to make the move happen after he removed all references to Brentford from his social media, unfollowed the club, and changed his Instagram profile picture to black.
