China's ball control ability is relatively low. If you can't control the ball well, it will be difficult to have enough time to find the fighter plane that attacked the goal. In domestic leagues, some players can control the ball properly and take the initiative to attack or contain their opponents. However, in the World Cup, with the improvement of the opponent's snatch ability, China's individual ball control behavior is rare, and the success of ball control is even rarer. In our possession time, we pass the ball more in the backcourt. In the World Cup, China had an average possession rate of 46% in three matches. Compared with their Asian brothers, South Korea and Japan, they hold more than 60% of the ball, which is far behind China. In terms of individual ball control, the average individual ball control time of Korean and Japanese teams is twice that of China. On the other hand, the poor ball control ability of China players has also led to the increase of the game timeout, although there are many factors that cause the timeout, such as dribbling out of bounds, passing and shooting out of bounds, and so on. 200 1 National Football Team A threw foul balls 3 1.6 times on average, while in 2000 ~ 200 1, the Chinese Super League threw foul balls only 19.5 times on average, and the 16 World Cup threw foul balls 22.3 times on average (Table 4, Table 4 Category of average throwing times per game: 200 1 year A League (2 1 game) 3 1.6 0 1 ~ 02 Premier League (15 games)19.5/kloc-0. 22.3 Comparison of Athletes' Physical Fitness Modern football requires athletes to maintain exuberant wit, strong physical strength, fast running, constant technical movements and slow brain reaction when playing a game every 2-3 days, that is, 90 minutes or even 120 minutes. Therefore, good physical fitness is an important guarantee for technical and tactical play. At present, China football players have little exercise, low intensity and slow speed in daily training. When they compete with foreign strong teams, because of their good physical quality and high speed, they are always dragged down by their opponents, which leads to passivity. In domestic leagues, due to the poor physical fitness of both sides, many players without the ball can't actively run to contain each other or meet their companions, so the whole game is slow. To improve the level of competition, it is necessary to increase the intensity and quantity of training and make the usual training closer to the competition. However, many domestic clubs attach little importance to physical training. A few years ago, China Football Association took 12 minutes to reach the standard, but it was opposed by many clubs. On the other hand, the Korean team has always been called the "undead" in Asia, but from February to April this year, Korean players still carried out almost cruel physical training. During this period, the players endured considerable pain, but in a series of subsequent games and the World Cup, the Korean team finally tasted the sweetness. 3.2 Comparison of enterprising spirit of athletes China players generally lack enterprising spirit, which is manifested in the World Cup and domestic leagues. If they are not active in running, they will be easily discouraged when they encounter setbacks in the competition, and they will not fight to the end, and their awareness of make-up is not strong. In the World Cup, players may have a chance to score goals if they actively make up shots. This phenomenon can be found everywhere in domestic leagues. They even lack an indomitable spirit, and they don't actively fight. Some frontal fights and tackles are retaliatory non-technical actions, but the Korean team not only runs actively, but also shows a spirit of brave struggle and eternal victory. They fought actively and worked hard. Taking every game as their responsibility, they have the courage and determination to go forward bravely. Portugal has the tacit understanding that they can both advance as long as they draw in the last match of the World Cup group match. But the Koreans gave up this conservative idea, continued to forge ahead, worked hard and won the game. 3.3 Comparison of coaches: The coaches of football in China are generally not high, ranging from junior teams to youth teams and then to adult teams. Although many adult teams (A and B teams), including the national team, have spent a lot of money to hire some high-level foreign coaches in recent years, it is difficult for the team to become a big climate because of the players' low football literacy and technical and tactical level. After the athletes retired, many coaches of various echelons in China began to take charge of coaching. Because most of them lack enough theoretical knowledge, their professional level and quality are low. Although some coaches also obtained university diplomas, many of them went to the sports technical college or the nearest sports institute to study part-time when they were athletes, and got university diplomas in three or four years. In fact, these people often have to train or go out to participate in competitions, so they can't study systematically. What's more, the cultural quality of most athletes is relatively low. After they become coaches, their ability to understand various problems and study teaching and training is extremely limited. There is another situation. Some students who graduated from physical education colleges are coaches at the grassroots level, but because of their low level of playing football, they can't establish prestige in the team and can't lead the team well. Some of the coaches of various echelons in Germany are trained by the Institute of Physical Education, and some are coaches after retired athletes. However, this country attaches great importance to the training of coaches, and stipulates that any athlete (including the famous athlete beckenbauer) must go through systematic study and training, undergo strict examination and screening, and obtain the qualification certificate of coaches before taking up their posts. Because the country attaches great importance to basic education and has a good training and learning atmosphere, young athletes have a solid cultural foundation, which has laid a good foundation for playing football and being a coach in the future. 3.4 Comparison of Athlete Selection Many countries choose athletes in different ways. For example, clubs in Britain and Germany all have their own athletes of different ages, and select excellent coaches to train and guide young people, so that their adult teams can have a substantial reserve army. In South Korea and Japan, there are perfect league systems at all stages from primary school to middle school to university, and the training and competition systems of all schools are standardized, which provides a good way for professional teams and national teams at all levels to select talents. At present, the China Football Association also requires every club A, B to have its own second-line and third-line teams. However, most clubs are not football clubs in the full sense, but some enterprises take over the team temporarily in order to promote themselves and advertise. Therefore, many people find an amateur sports school football class nearby as their second-line and third-line teams. In fact, they pay little attention to the training of the youth team, and even rarely ask about the training of the youth team. We often see that some young players in our country often show good technical and tactical abilities in some competitions, but they have not made any progress in the adult teams. The results of the youth team are good, but they can't get up when they get to the adult team. This is mainly due to the existing management system in China.
