First, look at the gap in hard实力. South Korea’s total squad value is €137 million, while South Africa’s is only €49 million — nearly a threefold difference. In the FIFA rankings, South Korea are 23rd and South Africa are 60th; these are not teams in the same bracket. South Africa also have two key players suspended: defensive midfielder Siso and striker Zwane are both unavailable, which will weaken the midfield’s defensive intensity and the attack’s finishing ability.
Next, look at motivation. South Africa must win to qualify, so they will surely have to come forward. But what level is their attack really at? In the first two rounds they scored only one goal, and that came from a midfielder’s long-range shot that was basically a lucky strike. Their forwards still haven’t opened their account. They are relying on Foster alone, and if South Korea can keep him quiet, South Africa will basically pose no threat.
For South Korea, a draw is enough to advance, but that does not mean they will play conservatively. With Son Heung-min and Lee Kang-in in the lineup, against South Africa’s defense, as long as they perform normally, goals will come sooner or later. South Korea also want to finish second in the group so they can get a more manageable opponent in the knockout stage, so there is no need to settle deliberately for a draw.
Of course, there is some risk. If South Korea think a draw is enough and play too cautiously, they might only win by one goal and fail to cover. But overall, with the 0.75 handicap and the difference in quality and tactical approach between the two sides, I believe South Korea are more likely to win and cover the spread.
