Rodriguez is currently on the books at Greek Super League outfit AEK Athens. 

The 27-year-old made the move to Greece from Santos in 2016 after four years with the Brazilian club. 

In that time he spent two seasons out on loan - one in Argentina with Estudiantes, and one in Malaysia with Johor Darul Ta'zim. 

Reports out of Greece suggest Newcastle are in advanced negotiations to secure the Argentinean's signature. 

Rodriguez is reportedly very keen on the move, which would see him become the third Argentine in the A-League in 2017/18, along with Melbourne City's Fernando Brandan and Melbourne Victory's Matias Sanchez. 

The Jets - under new coach Ernie Merick - currently have three visa spots left to fill on their roster.
