The coach returns to his hometown of Newcastle on Tuesday, where the No. 7 Canadians battle fourth-ranked Sweden to wrap up the preliminary round.
A victory would ensure the Canadians — with a 2-1 loss to Japan and 3-0 victory over South Africa — a spot in the quarter-finals, but they could also move through on goal differential.
Pacing the sidelines of what's officially now called Sports Direct Arena — or better known as St. James' Park, home of Newcastle United — will be a special moment for Canada's 37-year-old coach.
"I stood on Gallowgate End (the stadium's southern stand) with my dad when I was five years old," Herdman said the day the draw was announced. "This is an amazing opportunity, a dream come true, local lad leads his team out at the ground he went to as a kid to watch his favourite team.
"I watched from the stand, always dreamed of leading a team out there one day ... Brilliant."
Herdman hoped Newcastle fans would embrace the Canadians, and make them the "darlings of the northeast."
The Canadians face a tough test against the Swedes, bronze medallists at last summer's World Cup and perennial top-four finishers in any major tournament.
"They know how to win football matches, they're very organized, disciplined," Herdman said. "Greatest strength is they're very disciplined and organized around what they do, that might also be their greatest weakness.
"But if you are loose with your possession, you're in big trouble."
Sweden beat South Africa 4-1 and played Japan to a 0-0 draw.
