His coach insists that the Swiss were well short of their best as they came from behind to secure the win and believes they can only get better as they acclimatise to the Brazilian conditions.
"I almost exploded at the end. It was a huge relief," admitted Hitzfeld.
"Ecuador were more fresh at the end, as they are better used to playing at altitude. We feel as though we still need a few more games before we will be fully acclimatised.
"But the team fought back and we kept our patience. I told the players at the break that we can score a goal at any time. We have this potential."
Switzerland face a clash with France in Salvador on Friday and will complete their group campaign against Honduras in Manaus on June 25.
