Argentina head coach Lionel Scaloni was upset following his side’s victory and pointed blame at those in charge of hosting.
"Two days ago (the surface) was fake, and then they parched panels of grass together. It's painted to appear nicer than it is," Scaloni said. "The weird thing is we knew months ago we'd play here, so maybe things could've been done about the pitch quicker.
"The state of the pitch was a disaster. Very bumpy. We must improve in this aspect,” Martínez said. “Otherwise, Copa América will always appear at a lower level than the European Championship."
Argentina defender Cristian Romero echoed the opinions of Martínez and Scaloni about the playing surface.
“Having to play this competition on such an ugly field like this is unfortunate,” Romero said. “The field conditions were very ugly.”
Canada’s Kamal Miller didn’t feature in Thursday’s game but did go through warmups on the field.
"(The field) felt like walking on a stage, as if it was hollow," Miller said.
