One of these two teams is expected to win the 2017 CONCACAF Men's U-17 Championship, and they are expected to meet again in the final on May 7 to settle the question of which one of them is the best in regional soccer at this level.
But first, they must play each other in the group stage. This game will help to determine which of these teams wins Group C. They both won their opening matches - against Jamaica and El Salvador, respectively - by a large margin: the US put five goals past the Jamaicans; Mexico scored six against the Salvadorans. They are both expected to win their final group stage matches in similar style. So this game is the chance for one team to establish early bragging rights and lay down a marker for the re-match it is assumed will take place in the final.
These teams met in August of last year, in Mexico City. The USA opened the scoring, but El Tri won the match, 6-3. But it has been about eight months since that game, there will be a few different faces on the field this time around, and those who played in Mexico City are at a different stage in their development.
And a few of the players in this match are doubtless just at the beginning of their involvement in this rivalry. These two cohorts can expect to track each other through this year's U-17 Championship, perhaps the U-17 World Cup later in 2017, the 2019 CONCACAF U-20 Championship, that year's U-20 World Cup, perhaps an Olympic qualifying tournament thereafter, and the regular meetings between these sides at the senior men's national team level.
Perhaps in 2026, Mexico and the USA will meet in a co-hosted World Cup, with a couple of players on both sides looking settle matters raised during the 2017 CONCACAF U-17 Championship. The next iteration of the Mexico-USA rivalry will begin its development at this tournament.
