Both sides lost the semis within 90 minutes. Argentina lost their last two Copa America finals against Chile, so they are motivated to take revenge in this 3rd-place play-off. Besides, they remained unbeaten in these two teams’ last 7 face-offs in regular time with 5 wins and 2 draws.
On the other hand, Chile’s offense has been underwhelming lately, so they may find it hard to pose threat to Argentina.
Therefore Argentina should be able to win this game in regular time.
