Excluding goals scored in penalty shootouts and referring strictly to those scored in Regulation or Extra time. What will be the largest goal difference in a single game, between 2 teams?

Market will close on the eve of the tournament, at midnight CDT on June 10th. Final resolution will occur after the final on July 19th.

In the event that the tournament is unexpectedly truncated, postponed or paused due to things such as Pandemic, Terrorist Activity, Mass Shooting, Extreme Weather Emergency, Alien Invasion, Foreign Military Invasion, Coup d'état and etcetera. I will weigh the decision but most likely resolve the market to N/A and return all wagers.
