Italian side Napoli are the latest team to show interest in the 23-year-old Norway international, who cost the Blades £22m in January 2020.
The club are struggling to find a buyer willing to meet their £35m asking price however, with Napoli the latest club to stand firm on their bid.
Elsewhere, Aaron Ramsdale is expected to be the subject of a bid from Arsenal following the conclusion of the European Championships.
