If there is no suitable candidate for the full-back, it will simply not be set up, relying on the winger back defense and the filling of the back waist to solve the problem of midfield side defense, and the setting of the three backs also makes Wang Jiayu, whose advantages and disadvantages are very obvious, get a stable starting opportunity, and the midfield organization of the Chinese team has been greatly improved, and this in Hiddink's view, it will also benefit greatly because of the home whistle, because Wang Jiayu's biggest weakness is the serious lack of physical confrontation, as long as the whistle blows more tightly on the body, his performance will be greatly improved.

On this basis, Hiddink believes that the national football team is fully capable of fighting with those world-class teams that are not good at midfield control without falling behind, even if they meet those who are good at controlling the ball, such as the Spanish team, the Chinese team can greatly weaken the opponent's advantage after strengthening the midfield control

However, in order to discharge the "4+2" midfield configuration, the national football team has also paid a lot of price, first of all, the frequent return of wingers will inevitably lead to excessive physical consumption, but Hiddink has always been good at physical training, under his devil training, even Xie Wenjun, who has always had the worst physical fitness in the front four of the national football team, can now run more than 10,000 meters per game, plus with the continuous accumulation of game experience, his physical distribution in the game is more reasonable than before, so as long as he does not play overtime, Even if he needs to defend often, his physical strength is completely sufficient, not to mention that his main position is still the center, which is generally not so much consumption. As for the others, not to mention, Gao Jun can't run to death, and the physical fitness of the martial arts king is not bad, and although the physical fitness of Xue Lin is slightly worse, this guy has a tendency to get older and more demonic in recent years, and the rationality of physical fitness distribution is catching up with Gao Jun, so there is no need to worry at all.

Even if there is a continuous hard fight, because the four main players in the front court of the Chinese team can be qualified for the three positions of center, winger and forward midfield. Therefore, it is only necessary to lift Wang Jiayu to the forward position to free up a position, and the rotation can be realized to ensure that the front foursome always have enough physical strength.

The shortcomings of the back three in defense, especially the loopholes in the ribs of the penalty area, can only be solved by relying on the filling of the back waist, and the back three formation is very different from the back four, the back four formation is two people in the middle, once broken through by the opponent, it will almost certainly be a single knife. The possibility of conceding a goal is huge, and even if the back three formation is breached, there are still drag-back central defenders who can come up to defend it, and the threat is relatively small, although the crowd will feel a lot of pressure watching the opponent frequently enter the box

In fact, the main reason why Hiddink chose the three-back formation is that the current staffing on the national football backline is more suitable for playing three-back, because the four-back formation has higher requirements for the personal ability of the two central defenders, and the current backline of Chinese football is also in a situation where there is a shortage of green and yellow.

Feng Xiaoting is now getting old, and she will retire by 2018; And Zhao Ming also went downhill after a major injury that lasted for nearly a season, and it was also difficult to hold on until 2018; The central defender Lyon who has emerged in the Jiangsu Shuntian team in the past two years is in good physical condition and has good technical awareness. But from the fact that he never had the opportunity to stay in the United States, it can be seen that the strength is limited after all, with the Chinese team's pursuit of making a difference in the 2018 World Cup, it is difficult for Lyon to pick up the main beam unless it can make significant progress in two years.

As for Bai Jiajun, who has surprised countless fans, his state after returning to China is definitely not as good as when he was in Barcelona, and his height has always been a huge hard injury. When encountering a German team with air superiority and the like, it was definitely a rhythm that was blown up in minutes

It is precisely because there is no central defender in the country who can completely reassure Hiddink. He had to let Yu Hai, who has now become a world-class midfielder, drop back to the central defender position, but even then it could only solve the vacancy in one position. Therefore, in a sense, Hiddink has no choice but to let the national football team switch to a three-back formation, after all, the three-back formation has much lower requirements for the personal ability of the central defender, especially the air defense ability, than the four-back formation, and only the dragging back central defender is particularly important, and the national football team now has Yu Hai, a suitable candidate.

Furthermore. There is no fullback setting in the three-back formation, which liberates the original main right-back Zhang Linpeng, this kid is strong, fierce in defense and the speed is okay, but the bouncing header is slightly worse, and the central defender who plays the four-back formation is not suitable. The right-back in the back three is tailor-made, and although he has the best long-range shooting ability in the country and therefore has a lot less opportunities to perform, it is generally quite a good choice. For Bai Jiajun, who has more distinctive characteristics, the national football team's change to a three-back formation has completely resolved his embarrassing situation, and the characteristics of positive grabbing, excellent prediction, and accurate and fierce feet can be maximized, while the weaknesses of physical fitness and air defense can be avoided to a large extent

For Yu Hai, who has both attack and defense, playing as a drag-back central defender will definitely suffer a lot of loss in game statistics, but his role in the team's tactical system is greater than that of the midfielder. And although he rarely played as a central defender in the club during this time, the dragging central defender who had to be responsible for the ball at the back was actually very close to his most suitable free man position, and Hiddink allowed him to decide whether to change to a free man when the score was behind, so Yu Hai was also like a fish in water in the new formation of the national football team.

Guus Hiddink's three-man formation has also had a significant impact on one position, which is that as the saying goes, it can be worth the goalkeeper position in the top half of the team, and because of the presence of dragging the central defenders, the goalkeeper's ability to attack and range of motion has become less important, and the ability to save has become an even more important indicator. In this case, the first genius cultivated by Gao Jun Football School, the young goalkeeper Zhang Bin, who was born in 1997, challenged Wang Dalei, the main goalkeeper of the previous national team

Unlike the general youth training route in the early stage, which pays more attention to the cultivation of offensive players, the football school opened by Gao Jun focuses on cultivating defensive players at the beginning, which is actually a very realistic consideration, as the Chinese Super League becomes more and more expensive, the midfield of each team is basically occupied by strong foreign aid, and young players want to stand out in the competition, it is even more difficult than ascending to the sky, so for the future prospects of the young players in the football school, Gao Jun can only find another way, focusing on cultivating defensive players, and the players trained by this route may not seem to have any aura, but at least the defense is hard and the game is active, which any coach will like, and the Chinese Super League and the Chinese Super League are currently seriously lacking qualified defensive players, so their future employment will naturally be much easier.

It is important to know that due to China's special national conditions, after the youth training reaches the stage of football school, almost all the students want to become professional football players, and if they fail to succeed in employment, half of their lives will be ruined. Although it only needs to cultivate one or two big stars to play an exemplary role, there is no worry that there are no parents who are eager to get rich to send their children over, but in a responsible attitude, the students have a high enough employment rate after graduation to make Gao Jun feel at ease, as for the genius, he must be happy to meet him, even if he can't, his football school can also develop steadily, this is the football school development strategy that Gao Jun has long determined.

Speaking of unintentional insertion, when Zhang Bin first entered the football school, because he quickly showed excellent ball prediction and defensive position, he soon became the central defender of the football school's key training, but unexpectedly, this child who was only 1.7 meters tall when he entered the school has not yet entered the high-speed development period, and his figure accelerated unexpectedly after entering the school, and his height had reached 1.90 meters at the age of 16. With the body shape of the Chinese, this height is already a little too tall for the central defender, and this kid has not stopped growing taller, plus Zhang Bin's arm span is amazing, more large, and the reaction is quite fast, so the coaches combined, simply let him try to be a goalkeeper?

As a result, this test is terrible, this kid only took a year to become the best goalkeeper in the Gao Jun Football School, and was successfully selected as the national youth to become the main goalkeeper, and then was bought by the Guangzhou Hengda team with 10 million yuan in cash + additional terms worth 20 million yuan, and only one year later seized the opportunity to squeeze out the second national gate Zeng Cheng who had stayed abroad for many years to become the club's main goalkeeper. Although the reaction speed is not top-notch, but Zhang Bin's outstanding landing point prediction and sense of position have been fully demonstrated in the Chinese Super League and AFC Champions League games, because of his tall stature, as long as he does not have problems with the position, he can make the opponent's shooting pressure greatly increased, because the angle of the high gate will naturally have an advantage. Coupled with Zhang Bin's outstanding psychological quality, which is rare among his peers in China, and the more critical the game and difficult situations, the more he can play at a higher level, which quickly attracted Hiddink's attention and called him into the national team.

However, Zhang Bin also has a relatively obvious weakness, that is, his speed is not fast, so there is a big man as high as 1.94 meters, but the range of movement is not very large, which is obviously not as good as Wang Dalei. However, after Hiddink adjusted the playing style of the national football team, Zhang Bin's weaknesses were largely covered, and he was still in the period of rapid growth, improving almost every day, and finally posed a challenge to Wang Dalei's main goalkeeper position.

However, the reason for this situation is also related to Wang Dalei's own declining state. After the Dresden Dynamo team really became a first-class team in the Bundesliga, due to the improvement of the club's goals, Wang Dalei's strength became more and more insufficient. As a result, after Magath left the Dresden Dynamo team, Wang Dalei was quickly purged, and although the subsequent development cannot be said to be very bad, it was not very smooth, and in the 2016/2017 season, he suffered another serious injury, and the club's main position was gone after the injury, which had a great impact on Wang Dalei's competitive state.
