Defender Erik Pieters will leave PSV Eindhoven for Newcastle United in the coming days, according to his agent Piet van der Pol.
The 23-year-old has been linked with a move to St James' Park during this summer's transfer window and is earmarked to replace Jose Enrique, who left for Liverpool earlier this month.
"Newcastle's interest is very serious and Erik finds the club a real challenge," Van der Pol told the Dutch media.
"I don't know the exact numbers of Newcastle's offer, but I'm pretty sure that the transfer will go ahead."
Pieters, a Dutch international, has been with PSV since 2008 and has established himself as one of the better players in his position in the Eredivisie.
