Newcastle have signed Denmark Under-21s striker William Osula from Sheffield United for a fee rising to £15million.
The 21-year-old played 21 times for the Blades in the Premier League as they were relegated last season, having spent the previous campaign on loan at Derby in League One.
Osula began his career in the youth set-up of his hometown club Copenhagen before moving to South Yorkshire in 2018.
'It's a big club, a great club, so I'm very happy for the opportunity to join Newcastle United,' he told the club's website.
'It's a great opportunity, and as soon as I heard about Newcastle's interest I knew I had to take the chance to join this club if it came.
Osula, 21, is a Denmark Under 21 international and has been with the Blades since 2018
Manager Eddie Howe said: 'William is a talented young forward with all the attributes to be an exciting player for Newcastle United.
'We have watched his development closely and we are delighted to have the opportunity to work with him in this next step in his career.'
Mail Sport understands the fee for Osula is £10m up front, with up to £5m in add-ons.
