During a pre-match press conference, Scaloni told reporters, "In the opening match of the Copa America or any important tournament like this one, there are not easy matches."
"Of course, Colombia is a very good team and we will take our precautions, but we have to think in our game and not in our rival's one, then as I mentioned before, we will take our precautions, but we have a clear game plan," he added.
Scaloni echoed the defender's description of Argentina's all-time top scorer Messi, who has been unable to replicate his achievements with Barcelona for his country.
"I want to emphasise his enthusiasm to play football. He was born to play football, he was born to win. We are impressed by his enthusiasm and the fact he is here sharing that desire to win with us makes us enormously happy," Scaloni said.
Scaloni has been in temporary charge since the World Cup and has expressed a desire to stay in the job after the Copa America, but said he would not be judged for his results alone.
"The most important thing is not just the results but how you get them, it's important that the fans can identify themselves with the team and like the way we play," he added.
