Gonzalo Higuain does not believe Argentina can take Panama lightly despite Lionel Messi being set to return when they meet in the Copa America Centenario at Soldier Field on Friday.
Panama ran out 2-1 winners in their Group D opener against Bolivia, with Argentina joining them at the top of the group after beating Chile by the same scoreline in a repeat of the 2015 final.
Gerardo Martino's team had to do without talisman Messi as the Barcelona star struggled with a persistent back injury.
"We had to win because it's a tough Copa. Great teams are playing and it was important to start with three points. Then you can let Leo recover and play when he is well," he told Ole.
"It was an important result, but we must not overlook any opponent. It's a very strong Copa and all matches are going to be extremely difficult," continued Higuain.
"We saw a compact and tough team. They are physically strong, with players that play well in space and they are a team that will generate threats."
"We are not scared of facing Argentina. They are the runners-up of the World Cup and the Copa America, but do not scare us," he said.
"When you're working with a team you cannot change the way they have played for two years."
