Newcastle United have signed Denmark Under-21 striker William Osula from Sheffield United.

The 21-year-old joins the Magpies for a reported fee of £15m, having scored three goals in 31 senior appearances for the Blades.

The striker, who has five caps for Denmark U21s, made 21 Premier League appearances for Chris Wilder’s side last term as the Blades were relegated to the Championship.

“It’s a big club, a great club, so I’m very happy for the opportunity to join Newcastle United,” said Osula.

“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.”

Newcastle manager Eddie Howe says the club have been tracking Osula for some time.

“William is a talented young forward with all the attributes to be an exciting player for Newcastle United,” said Howe.

“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.”

Osula is Newcastle’s sixth signing of the summer, following the arrivals of Miodrag Pivas, Odysseas Vlachodimos, John Ruddy, Lloyd Kelly and Lewis Hall.
