The 25-year-old started just 10 times for Atletico Madrid in La Liga last season but Alan Pardew is ready to offer the Belgian a regular role in central defense.
The 25-year-old joined Atletico Madrid last summer, but he was limited to just 10 starts in La Liga and a number of those were in his unfavored position of fullback.
A move to Newcastle will afford Alderweireld the chance to flourish in his natural position of center back, where he spent four years as a key player for Ajax before joining the Spanish side.

Arsenal, Liverpool, Tottenham, Southampton have all been strongly linked with the defender, while rival Sunderland had also been hoping to lure him to the northeast.
But Goal understands that he is set to opt for a move to Newcastle after talking with former Ajax teammates Siem de Jong and Vurnon Anita, both now at St. James' Park. Alderweireld will join on an initial loan and Newcastle will have the option to make the move permanent.
Alderweireld's arrival could see Mapou Yanga-Mbiwa head out of the club, with Roma showing a strong interest.
