Vietnam U23 lost against China U23 0-3 in the semifinals.
The turning point came in the 2nd half when Vietnam conceded a goal due to a turnover, and then had a player sent off in the final 15 minutes, leaving them with only ten players.
However it was a quite good run in this competition. They surprised many opponents even stronger then them. This generation of players is good and can have an interesting future.
For this game a big turnover is expected from coach Kim Sang-sik, since 2 regular key defenders Pham Le Duc and Huu Minh will be out due suspensions and injuries.
South Korea U23 in other hand lost against Japan U23 1-0. Their pressing and possession were impressive, though they lacked the ability to create truly dangerous scoring opportunities. They were tipped as favorites to win the trophy among with Australia and Japan, but a difficult draw against reiging champions put them out.
In terms of overall strength, South Korea U23 have a big edge against Vietnam. If they can improve their finishing efficiency, they should be able to defeat a Vietnam U23 team that struggles against high intensity teams.
I expect an open game from both sides and using many rotations players.

在半决赛中，越南U23以0比3输给了中国U23。
转折点出现在下半场，越南队因失误失球，在最后15分钟有一名球员被红牌罚下，只剩下10名球员。
然而，它在这场比赛中表现得相当不错。他们使许多比他们更强大的对手感到惊讶。这一代球员很好，未来会很有趣。
由于两名主力后卫范乐德和胡明将因停赛和伤病缺阵，本场比赛主教练金相植预计会有很大的失误。
另一方面，韩国U23以0比1输给了日本U23。他们的压迫和控球令人印象深刻，尽管他们缺乏创造真正危险得分机会的能力。在与澳大利亚和日本的比赛中，他们被认为是夺冠热门，但一场与卫冕冠军的艰难平局使他们出局。
就整体实力而言，韩国U23对越南有很大的优势。如果能提高射门效率，应该能战胜与高强度球队较量的越南U23队。
我希望双方都能打一场开放的比赛，并且使用很多轮换球员。
