Holders Chile join group winners Argentina in Copa America Centenario knock-out stage
Holders Chile , inspired by Arsenal's Alexis Sanchez, joined group winners Argentina in the Copa America Centenario knock-out stage with both sides winning their final games in Group D.
Chile advanced to the Copa America quarter-finals on Tuesday after two goals in the first half from Eduardo Vargas and two in the second from Alexis Sanchez gave them a 4-2 win over Panama, while Argentina took top spot by beating Bolivia 3-0 in Group D.
Defending champions Chile, as runners-up, will play Mexico in the next round on Saturday with group winners Argentina facing Venezuela the same day.
"This was important for me and for the team," said Chile's Vargas. "It has boosted our confidence for the games to come.
"We are Copa America champions but we haven't played as well as we did in the last Copa America and this will give us confidence."
Chile went behind to an early goal but roared back thanks to outstanding performances from their front pair, who ran the Panamanian defence ragged.
Panama took the lead in the fourth minute after a mistake by Chilean goalkeeper Claudio Bravo, who let Miguel Camargo's shot from almost 30 yards squirm through his hands and into the net.
Chile fought back and were soon 2-1 up.
Artur Vidal and Sanchez worked a one-two in the box after 14 minutes and Sanchez's shot was only parried by Jaime Penedo and Vargas followed up to smash it home.
Three minutes before half time striker Vargas rose to glance home a header to put Chile ahead.
Sanchez was in captivating form and scored one of the goals of the tournament after 49 minutes.
Vargas was the provider this time, creating space for himself in the box before chipping to Sanchez, who volleyed home in spectacular fashion.
Panama kept fighting and pulled one back after 74 minutes and again Bravo was at fault, failing to stop Abdiel Arroyo's header from going in at his near post.
Sanchez had the last word, however, when he rose unmarked to head home a cross with two minutes left to make it 4-2.
In Seattle, few were expecting anything other than an Argentine win over already-eliminated Bolivia and most of the attention was focused on whether Lionel Messi would surpass Gabriel Batistuta's record of 54 goals for his country.
The closest Messi came to scoring was from a free kick in the 61st minute but his curled effort sailed just wide.
