South Korea Under-23s take on Mexico Under-23s in the quarter-finals of the Olympic Games on Saturday, with both teams aiming to reach the semi-final of the competition for the second time in their respective histories.
South Korea earned the bronze medal at the 2012 Olympics in London, with Mexico beating Brazil in the final to win gold in the same year.
After losing 1-0 to New Zealand in their opening match of this year's Olympics, South Korea magnificently bounced back to win both of their ensuing matches and qualify as Group B winners.
Kim Hak-bum's side achieved the feat in some style, too, thrashing Romania 4-0 and Honduras 6-0 to seriously lay down a marker as potential winners this year in Tokyo.
Having missed a series of decent chances in the defeat to New Zealand, Kim's attackers clearly used this as motivation to inflict misery on their next opponents, but the 61-year-old will be hoping that they have not already peaked ahead of a tricky test against Mexico.
However, given that some of Mexico's most talented youngsters are competing for the senior team in the Gold Cup, the Asian side will sense a serious opportunity to reach the final four for the second time in three Olympics.
Indeed, having been drawn in a group alongside the hosts Japan and world champions France, Mexico have done magnificently well to reach this stage under the circumstances.
As already alluded to, head coach Jaime Lozano's hand has been limited by the fact that the senior side are involved in the Gold Cup, which it would be fair to say has largely taken priority in the eyes of the Mexican Football Federation.
As such, Mexico perhaps lack the strength in depth which they boasted in their triumphant 2012 campaign, although they have been able to call upon experienced goalkeeper Guillermo Ochoa - who has 114 senior caps - as one of their three over-age players.
However, El Tricolor still managed to thrash France 4-1 and South Africa 3-0 either side of losing to hosts Japan 2-1 to progress to the knockout stages, and they will fancy their chances against South Korea, whom they gained as many points as despite being in a tougher group.
For South Korea, Kim's main decision could be whether to opt for a 4-4-2 formation or the 4-1-4-1 system which worked to great effect last time out against Honduras.
Should he side with the latter as expected, Lee Kang-in may have to wait to enter the game as a substitute once again, having scored three goals in his last two appearances from the bench.
Mexico, meanwhile, will be without the suspended Carlos Rodriguez after the midfielder received a straight red card against South Africa.
South Korea Under-23s possible starting lineup:
Bum-Keun; Young-woo, Tae-uk, Ji-soo, Yoon-sung; Du-jae; Dong-jun, Jin-kyu, Chang-hoon, Jin-ya; Ui-jo
Mexico Under-23s possible starting lineup:
Ochoa; Lorona, Montes, Angulo, Sanchez; Romo, Esquivel, Cordova; Antuna, Martin, Vega
We say: South Korea Under-23s 2-2 Mexico Under-23s
There appears to be very little to split these two sides, so we can envisage it going the distance.
Both sides possess plenty of attacking quality, so it should be an entertaining quarter-final for the neutrals.
