Although Japan's U23 scored from the top spot in Group B with a record of winning all three games, it lost to Uzbekistan's U23 in the first round of the knockout round with four goals and finally stopped in the quarterfinals.

2018 U23 Asian Championships has ended the quarter-finals stage. Although Japan U23 has won all three games from the top of Group B, it lost four goals to Uzbekistan U23 in the first round of the knockout round, and finally stopped in the quarterfinals. Since this Japanese U23 team was also defeated by the Chinese team 2-1 in the U23 Asian Championship qualifiers held in July last year, the outside world has had speculations about whether Japan's football strength has declined and whether its talent reserves are broken. So what is the truth? Let us objectively analyze and review the performance of Japan's U23 in this Asian Championship through data.

Japan's "U20"

, which is absent from dual cores. Among the 16 participating countries in this U23 Asian Championship, Japan is the youngest team with the average age, with an average age of only 19.5 years old. In this Asian Championships, Japan did not send a "real" U23 national team, but instead sent a younger U21 team to fight. In Japan's 23-man roster, 8 were under 20 years old. The oldest Bankura Huang, the team, will not be 21 years old until the 27th of this month.

Compared with the competitors of this event, Japan almost sent a "U20" youth team to fight for the big ones. In the end, the Uzbekistan U23 team, which eventually eliminated Japan, reached an average age of 21.1 years, 1.6 years older than Japan, while the average age of the host China U23 is 21.3 years older than Japan.

In addition to the younger team, Japan's U23 is also facing the unfavorable situation of absent from many core players. On the defense line, Kashima Suns defender Yuta Nakayama, who won the best young player in the J League last season, was given a rest and did not go to China with Japan's U23, which also made the team lose the defensive needle on the defense line.

midfield front court, Anlu , which had a stunning performance at the U20 World Cup last year, was also not included in the Asian Championships list because of following the club training. 19-year-old Doan Ryu is currently playing in Groningen, the Dutch Eredivisie. As one of the best attackers of the same age in Japan, his absence undoubtedly reduced the offensive strength of Japan's U23 in this Asian Championship. In addition to the offense and defense, Ariki and Nakayama Akita were all absent, Japanese genius Kubo Kaikai, who came from Ramasia youth training, also missed the Asian Championships due to personal reasons.

Group match: Pass control crushes, weak forward line

Focus on transmission control and delicate cooperation is a technical and tactical feature that Japanese football has always adhered to. The Japanese U23 who went to this Asian Championship is no exception. In the first two rounds of the group stage, Japan's U23 defeated Palestinian U23 and Thailand's U23 in a row with two goals from Bancang Huang, 1-0, thus ensuring the group qualifying in advance.

Although both games were small wins with one goal, Japan's advantages in scenes and statistics completely crushed the opponent in both games. In the first match of Palestine, Japan's U23 passed 731 live balls in the game, and the pass success rate was as high as an astonishing 91%. In the second game, Japan U23 passed the ball lively in the game again, breaking through the 700 mark (714 times), more than twice that of Thailand (329 times). In terms of shooting, the Japanese team html 20 shots and 7 shots, while Thailand only completed 2 shots. Judging from the first two games of the group stage, although there are not many goals, the young Japanese team has fully demonstrated its tactical characteristics.

faces North Korea's U23 in the last round. Japan's U23, which has already qualified early, has replaced as many as ten starters compared to the second game. The coach Mori Boichi gave the bench full opportunity to perform. In the end, the Japanese team, which played in a rotational lineup, defeated North Korea 3-1 and won three consecutive victories in the group stage.

From the comparison of average data in the three group matches, the skilled and capable Japanese U23 has a big lead in both the pass control and the shooting stages. Although the average total running distance is slightly behind, the average high-intensity running (speed greater than 21km/h) is more than 300 meters ahead of the opponent. Among the data rankings of all 16 teams in the group stage, Japan U23 ranked second in all four statistics: shooting, shooting, passing, and forward passing.

However, Japan U23 also has its own shortcomings. Among the team's five goals in the group stage, two defense players, Bankura Huang and Liu Guibo, contributed 3 goals, and only Sanhao Kanger scored 1 goal on the attack line. In addition, there was an opponent's self-missing goal. The weak forward performance and the long-term failure to score in the first two games have also become the biggest problems exposed by the team in this Asian Championship.

Knockout: The black eight-minute defeat in one blow

qualifies in the group, Japan U23 encountered the Central Asian powerhouse Uzbekistan U23, who once reached the quarterfinals of last year's World Youth Championship. Facing an opponent with an average age of nearly 2 years older than him, the Japanese team has obvious disadvantages in physical confrontation. Under the high-intensity game rhythm, Japan U23 has no way to play its advantages in passing and control.

From the 31st minute to the 39th minute of the first half, Uzbekistan scored three goals in 8 minutes, defeating Japan's U23 in one fell swoop. In the second half, Yahshiboyev scored his second goal in this game. The Japanese U23, who was unable to make up for the situation, could only swallow four goals and lose a crushing defeat.

Comparing the statistics of both sides of this game, Japan's U23 lags behind Uzbekistan's U23 almost in all directions, especially in terms of the success rate of peer-to-peer battles, Japan lags behind Uzbekistan by 24 percentage points. In this game, the Japanese team failed to stabilize their position in time after being broken by their opponents. They were eager to attack but were scored two more goals in a short period of time, which also exposed the lack of Japanese U23's game experience.

Review of the four games of this U23 Asian Championship, the Japanese team, which focuses on training, has fully trained its youth army. The young Japanese internationals not only showed good game content, but also exposed their own shortcomings. Although they suffered a four-goal loss against Uz, it can be foreseeable that this group of young people will definitely become an important fresh blood in Japanese football in the future.
