The Premier League duo are two surprise inclusions in the Albiceleste squad as the South American side prepare to face Saudi Arabia in a November international friendly
The Albiceleste take on Frank Rijkaard's men in Riyadh on November 14 and head coach Alejandro Sabella has made a number of surprising inclusions to his squad.
Latics forward Di Santo has never made a senior international appearance for his country, despite playing over 20 times for the Under-20s side. However, the 23-year-old looks set to finally get his opportunity after being called up following a string of impressive performances towards the end of last season and this term.
Magpies mainstay Coloccini has made 34 appearances for the national team and was called up to the side as recently as September when he was named in the squad for the World Cup qualifier with Paraguay.
