Argentina suffered a 2-0 defeat by Colombia on their Group B debut in Copa America 2019. Lionel Scaloni's men, with Messi leading the way, could not break down Colombia and were hit twice on the counter.
"It will take us time to accept this defeat and come to terms with it," said Messi, who didn't have a magical afternoon even though he was the best his team had to offer.
