Argentina’s star player Lionel Messi and his team stood aghast after their 2-0 loss to Colombia in Copa America, Brazil on Saturday.
Despite dominating the second half, Argentina could not make it to the Colombia net in their opening match.
Goals from Roger Martinez and Duvan Zapata in the final 20 minutes gave Colombia their first tournament victory over Argentina in 20 years.
Although Argentina dominated possession and created more chances in the second half, they rarely caused Colombia's goalkeeper David Ospina any serious concerns.
"In the first half, we retreated a little and were holding on, but in the second we really opened up," said Messi, the Argentina captain.
"Whenever you lose it's hard for us, we usually take it badly. Now we have to think about Paraguay," he said.
Argentina can still make the knock-out stages with games against Paraguay and Qatar and the Asian champions
