Unsurprisingly, two teams that have found it hard to score at this U-20 World Cup found it hard to score against each other.
Ultimately, a second yellow card for Alioune Gueye tipped the match Mexico's way. Playing 10 men for the final 20 minutes, and with fresh legs on the field for the last 10, El Tri managed to find the net in the 89th minute thanks to the poacher's instincts of Ronaldo Cisneros.
The last-gasp, 1-0 win seemed about right - most observers would have predicted a game decided by a single goal or penalties.
