Neither Mexico nor South Korea could find a goal in the opening 45 minutes of their 2012 Olympics campaign as they enter the interval all square.

Both sides struggled to create meaningful chances throughout the half, with Mexico creating a number of decent platforms without finding the killer final pass.

Of the few chances that there were in the first half an hour, Korea had perhaps the best sights of goal, but still failed to trouble Jose Corona in the Mexico goal.

The two sides go into the break tied at 0-0 knowing that a draw could hand the initiative in Group B to either Gabon or Switzerland, who face each other later today.
