Mexico had the U.S. under pressure early, even though the final score suggests a comfortable win. Canada can bring a similar problem when the U.S. tries to play out. Shaffelburg's movement on the left and Jonathan David's position in the box give that pressure a way to turn into chances. That matchup is the reason for this slip.
The U.S. found a route down its right against Mexico, but its first goal needed a goalkeeper spill. The next two came from Mexico giving the ball away near its own goal. Those finishes showed alertness, while the opening spell showed how difficult it was for the U.S. to move through a strong press.
Canada's recent goals against Peru came from wide deliveries that found Shaffelburg in scoring positions twice. David and Stephen Eustáquio remain in the squad alongside him. Pochettino has made major changes between the U.S. lineups in this window, making the contest between Canada's pressure and the U.S. buildup more telling than the run of scorelines.
