Walter Benítez was born in Chaco and played for Quilmes and PSV Eindhoven. He was shortlisted for the 2016 Rio Olympics, but an injury sidelined him from the competition.

He has been called up to the Argentina squad for the 2026 World Cup Qualifiers but did not play against Uruguay or Brazil. Lionel Scaloni needs a replacement for the world champion team for the upcoming Copa América and World Cup qualifiers that lead to the next World Cup.
