Agent Piet van der Pol says PSV Eindhoven fullback Erik Pieters is moving to Newcastle United.
The Holland international 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."
