Everton have made an enquiry, while Norwich have previously had a bid accepted for the defender, who looks certain to leave the Amsterdam Arena this summer.
Spartak Moscow have also had an offer of £5million accepted for the Belgian, and are set to offer wages of £60,000 a week.
Now it appears Newcastle are set to make an offer of their own, with boss Alan Pardew and Director of Football Joe Kinnear looking to complete only the club’s second signing of the summer.
Loic Remy has been the only player to arrive at St James’ Park this summer, with the French forward signing on a year long loan from QPR.
Alan Pardew has made no secret of his desire to strengthen his squad further, but has so far been left frustrated with attempted moves for Lyon striker Bafetimbi Gomis, and Aston Villa forward Darren Bent.
Pardew sees Alderweireld as the ideal signing, as the Belgian has both the ability to play at centre back and full back.
Meanwhile Newcastle are desperate to hold onto midfield playmaker Yohan Cabaye.
The French international has been linked with a move away from St James’ Park, with Manchester United reportedly showing an interest, however wealthy Paris St Germain have now emerged as the favourites for his signature.
