It won't be Lanzini who supplies it at the World Cup, however, and Sampaoli will now need to examine his back-ups to select a replacement for his injured star.
As reported by BBC Sport, Lanzini will miss the World Cup after suffering a ruptured anterior knee ligament injury in training.
River Plate midfielder Perez has taken his spot in Jorge Sampaoli's 23-man squad, having made three appearances at the last World Cup - he started in the semi-final and the final.More news: Alex Ovechkin: Caps treating every game like it's their last

Argentina's national team is due to travel to Russian Federation on Saturday for the World Cup.
Sampaoli originally named a 35-man provisional squad for Russian Federation and will likely select a replacement from the 12 players he dropped for his final group. Or alternatively, Boca Juniors' Cristian Pavón could find himself filling in for Lanzini in Argentina's opening group game against Iceland on Saturday 16th June.
It remains to be seen for how long Lanzini is on the sidelines, although it is likely that he will miss the start of next season, given the severity of his injury.
