Rafa Benitez is reportedly willing to sell the goalkeeper this summer.
The Magpies have been busy in the transfer window, as five new faces have already arrived at the club.
There has also been a major departure, as Andros Townsend elected to return to the Premier League via a move to Crystal Palace.
He could be the first of several to leave the club, with Moussa Sissoko and Georginio Wijnaldum also linked with big money exits.
Rafa Benitez would loathe losing either of those players, but according to the Daily Mail one man they are willing to sell is goalkeeper Krul as they have put him up for sale.
The Dutchman is currently battling his way back from a cruciate ligament injury picked up while on international duty back in October.
That injury ruled him out for most of last season and his absence saw the likes of Rob Elliot and Karl Darlow shining in his place.
Matz Sels has also arrived this summer meaning there is firm competition for places and they are reportedly allowing Krul to depart as a result.
