The South Koreans are now a game away from a guaranteed medal although they face a tough task on Tuesday night against a Brazil side who are strong favourites to be crowned champions, having twice come from behind to beat Honduras in the last eight.
The Selecao are a best price 4/9 (William Hill free £25 bet) to claim a gold medal and they have scored goals for fun all the way through the tournament, having managed three in all four of their matches against Honduras, Egypt, Belarus and New Zealand.
Leandro Damião and Neymar could be in a straight shoot-out to finish top goalscorer and the best price about Brazil winning this semi-final in normal time is 8/15 (Coral free bets), with South Korea available at a massive 13/2 (bet365) to claim victory.
In fairness to the Koreans, they were value for their win against Team GB and came through the group stage unbeaten after holding Mexico to a draw before a 2-1 win against Switzerland.
The bookies are finding it much harder to call the other semi-final, with Japan marginal favourites to oust Mexico and book their place in the Wembley final. The Japanese were far too strong for the Egyptians in their quarter final match and BetVictor go 31/20 that they ease through this clash at Wembley.
Nobody expected Spain to stumble at the group stage, although a stubborn Japanese rearguard and a vibrant counter-attacking strategy ensured that the Samurai Blue were far too good for La Roja, with Takashi Sekizuka’s side not conceding so far at the Olympics.
Yūki Ōtsu has been one of the stars of this tournament and the Borussia Mönchengladbach player is available at 9/1 to score the first goal of this game, with Mexico hoping that a certain Tottenham player can help them through to the final.
Tottenham supporters might not have seen the best of Giovani Dos Santos, although he has enjoyed himself playing for the national team and the Mexican is the 6/1 favourite to break the deadlock in this particular contest.
Perhaps Mexico are being underrated by the layers considering they won Group B which was a pretty tough section, while Senegal was no easy match and that man dos Santos ensured that the central American side were able to come through in extra-time.
Finally, the Top Goalscorer market looks interesting, with Brazil’s high-scoring ways suggesting that Moussa Konaté could be vulnerable on five goals, especially from Leandro Damião who needs two to overhaul him and odds of 15/8 look particularly enticing.
