The Copa America hosts turned on the style to ensure qualification for the quarter-finals as Group A winners with a 5-0 demolition of Bolivia in Santiago on Friday.
Both Chile, who had Vidal in their starting line-up, and Bolivia had already been assured of a place in the last eight after Ecuador's 2-1 victory over Mexico earlier in the day.
The hosts now face a quarter-final on Wednesday against the best-ranked, third-placed team from the first phase, most likely to be Uruguay or Paraguay.
