The Magpies have swooped to sign Georginio Wijnaldum and Aleksandar Mitrovic from PSV Eindhoven and Anderlecht respectively this summer, whilst another Anderlecht star is also poised to join Newcastle, with Chancel Mbemba awaiting work permit clearance.
Away from that, new manager Steve McClaren may look to add more new faces - and Manchester City's Humphreys is certainly a surprise name.
The Magpies may need new options at centre back but 16-year-old Humphreys is one for the future, despite impressing for City during their pre-season fixtures.
According to the Daily Mail, Newcastle are ready to make an offer for Humphreys, with the defender able to sign a professional contract at the end of August.
They could face competition from Everton and Manchester United though, with a number of Premier League clubs seemingly keen to sign Humphreys.
A talented young centre back with the potential to develop into a Premier League player, Humphreys' impressive displays during pre-season have put him on the radar of a number of clubs - and Newcastle will be hoping that he chooses them over their Premier League rivals.
