Paraguay-Korea Republic, Cairo, Monday 5 October, 20h00 (local time)
These two teams qualified for the Round of 16 as runners-up in their respective groups. It took Paraguay only two matches to get through to the knock-out stage, while Korea Republic needed a 3-0 win over USA in their final group match to secure their passage. Paraguay incidentally became only the second team in the history of the FIFA U-20 World Cup to get through the group stages despite two goalless draws (against Italy and Trinidad and Tobago). Near neighbours Columbia managed this feat in 2003 when they too finished second in their group after 0-0s against Egypt and England.
3 - This is the third time that Paraguay and Korea Republic are facing each other in a FIFA U-20 World Cup. The South Americans won both previous encounters, in the group stages in 1979 (3-0) and 2003 (1-0).
Korean attacker Kim Bo Kyung will turn 20 on 6 October, and will be hoping for an early birthday present in the shape of a quarter-final berth.
"Korea are a tough opponent. They have speedy players who run well with the ball, so we'll have to remain focused throughout the entire match. They are a lot like Egypt in the way they play, so I would not be surprised if it ends up being a similar match."
Adrian Coria, Paraguay striker
"Paraguay is one of a number of South American teams that are among the best in the world, and they eliminated Argentina in the qualifiers. They are strong, technically very gifted and the way they play is very clever. It will be a tougher test for us than what we faced in our group, but we've got through to the knock-out stage and from hereon in, who knows what will happen next?"
Hong Myung Bo, Korea Republic coach
