American Marsch, the former RB Leipzig and Leeds United manager has quickly installed his high-energy, hard-pressing style on the Canada team since taking over in May.

But he conceded that he could see his players were struggling to bring that approach in the New Jersey heat after a run of five games in the competition and accepted he needed a broader selection of players to call on.

"I think that the tournament caught up with us a little bit. Argentina rotated a lot of players throughout the tournament so... they weren't calling on the same players every match," he said.

"There's been heat, there's been travel, there's been a lot of challenges. In the end, we're still in the beginning of our process," he stressed.
