The game became a little feisty with several niggly fouls, but the young Reds remained composed as they soaked up pressure from the Mexicans and relied on quick counter-attacking moves, a tactic which paid off in the final minute of the game.
The ball was played out of defence quickly and Wilson roared away from the halfway line to draw the goalkeeper and slide the ball into the net. Game, set and match to United at 2-0.
There will be little respite for the young Reds and little time to savour the joy of victory as the second game follows tomorrow (Monday, 21:00 UK time) against Dallas Texans at the University of Texas’ Dallas campus. The local team lost their opening match in Bracket A, 1-0 to Japanese club Kashiwa Reysol.
