The new technological advance was confirmed in Moscow by CONMEBOL president Alexander Domínguez. “I like VAR and I believe it is here to stay,” Domínguez explained as he announced the decision.
The quarter-finals will take place between September 18 and October 4. The system will be implemented in all eight games. In 2017 VAR was used in the semi-finals (River-Lanús and Gremio-Barcelona) and in the deciding match (Gremio-Lanús).
The technology will also be present from the last eight onwards in the Copa Sudamericana as well as the Recopa Sudamericana. VAR will only be active in four instances: goals, penalties, red cards and confusion over a player's identity.
