Midfield
There are some interesting call-ups in the midfield zone, including the surprise selection of Guido Rodriguez, who has impressed at Tijuana in Mexico. West Ham's Manuel Lanzini and Leandro Paredes of Roma have also been called up for the first time.
Argentinian media reports suggest that Ever Banega has been earmarked for the deep-lying playmaker role taken up by Marcelo Diaz in Sampaoli's Chile side. There, Sampaoli generally preferred a narrow three or four-man midfield, but at Sevilla, he also utilised a 4-2-3-1 formation, so the midfield make-up is open to interpretation.
If it is a three-man midfield, a combination of Banega, a mixed midfielder such as Paredes or Lanzini and someone to provide attacking thrust such as Eduardo Salvio or Angel Di Maria seems a plausible setup.
Salvio and Di Maria could also potentially operate as wing-backs if a three-man defence is employed, although one would imagine it would be one or the other with a full-back on the other side rather than both in unison.
