Newcastle are set to sign Real Sociedad striker Alexander Isak for a club record fee of about £60m.
The Sweden international, 22, would boost the Magpies' attacking options given the injury record of Callum Wilson, who is awaiting results of a hamstring scan.
Ex-Borussia Dortmund player Isak has 44 goals in 132 appearances for Sociedad, and nine in 37 for his country.
Newcastle's transfer record is the £40m they paid for Joelinton in 2019.
The Brazilian striker-turned-midfielder was signed from German club Hoffenheim.
The club also paid £35m plus add-ons for fellow Brazilian midfielder Bruno Guimaraes last January but Isak's signing would be a significant shift from Newcastle's new owners, who took over the club in October and have taken a considered approach to the transfer market.
