The tightly contested encounter at Philadelphia Stadium saw both teams hit the woodwork four times before the Manchester United winger came off the bench to net the winner.
Despite the winning start, the 22-year-old insisted the team must remain focused as they prepare for the rest of the group stage.
“We needed that. We came here to make history. We still have two more matches ahead of us, and we need to approach them with the same mentality and try to win them,” Amad told by FIFA.com.
” We had to stay focused. We knew it was going to be a difficult match because we know the Ecuadorian players – they’re physically very strong. They caused us problems, of course, but we stayed composed and remained focused.”
Ivory Coast will face Germany in their next game at the Toronto Stadium on Saturday, 20 June.
