Newcastle United are investigating alleged racist chants against their players in the goalless draw at Den Haag.
The Mail on Sunday says the game was reportedly marred by racist chanting from some sections of the home crowd.
A Newcastle spokesman confirmed in a statement they will be addressing the issue with the Eredivisie outfit but will be doing so privately.
It read: "In relation to alleged racist chants reported during Newcastle United's friendly against Den Haag today, the club will be raising the matter with officials at Den Haag and the issue will be dealt with privately."
