Uruguay becomes the last team to open play at the 2021 Copa América, when it faces Lionel Messi's Argentina in Brasilia.
With a pair of five-team groups, the fixture list is slightly imbalanced, with three teams already having played two patches before Uruguay plays its first. La Celeste will be hoping to break out of its recent attacking slump, with Luis Suárez & Co. coming off a pair of 0-0 draws in World Cup qualifiers that preceded this tournament.
The two nations are the most successful in Copa América history, with Argentina's 14 titles only bettered by Uruguay's total of 15.
