Argentina and Uruguay go into Friday’s Copa America encounter with neither team having won in three games since November.
The two sides seem unsure about which players to select for the Group A game at the Mané Garrincha stadium in Brasilia.
The winner could ultimately go on to top the group and avoid an early knockout-stage meeting with defending champion Brazil, which is in Group B.
Argentina coach Lionel Scaloni has received criticism since his team’s opening 1-1 draw against Chile on Monday, a game that came a few days after a 2-2 draw with Colombia in World Cup qualifying.
Scaloni appears unsure whether to use three or four defenders against Uruguay. He could also bring back Cristian Romero in the center of his rearguard in place of Lucas Martínez Quarta.
If he opts for a line of three defenders, left-back Nicolás Tagliafico may miss out.
