The football hit the goal crossbar and bounced off.
Qin Xiong bowed his head and thought deeply about the reason for this phenomenon. This is not a special case, not an accident, but a situation with high probability when he tries his best to shoot.
He tried another kick to reduce his strength, and then he saw the football. He used to be familiar with the big arc and completed the flight trajectory without that irregular change. He steadily circled the outside line and fell into the goal.
He rested on her hips meditation again.
Obviously, the reason for the uncontrollable phenomenon is that he has found some strength to play football with him first
What’s bothering you?
Suddenly someone spoke behind him.
Qin Xiong twist a head to see that famous Fan Jiaer.
Qin Xiong politely greeted each other hello, sir
Fan Jiaer asked again, What’s bothering you?
Qin Xiong told the other side of his confusion and proved himself by three consecutive balls. Although one ball did not show the irregular trajectory, the other two balls showed the irregular trajectory when flying down.
Although Fan Jiaer looked as usual, his heart was more appreciative of Qin Xiong.
First of all, the other side is practicing here, which is a professional attitude. No manager doesn’t like such players.
Secondly, he watched Qin Xiong kick almost two Italian balls, which made him shine at the moment.
Yu Qinxiong is confused, and he can really answer it.
He walked over and picked up a football and said, Football flying in the air involves scientific knowledge, mainly fluid mechanics. Simply put, the flight trajectory of football is not controlled by you, including the front air resistance, the air suction behind the ball, the friction between the surrounding air and the football, and the rotating force of the air vortex on the football. First of all, you have to kick out the white football, that is, the football is the fastest at the moment after your foot kicks out the ball. At a certain speed, the flight trajectory of football is familiar to us, such as curved ball, straight ball, football will not produce too much or Even if the trajectory changes, we will ignore the subtle deviation changes by naked eye observation, but when the ball speed reaches fast enough or breaks through a critical point, the deviation of the football trajectory will change qualitatively under the influence of all kinds of air resistance, friction, rotation force and suction, which will make us visible to the naked eye. Congratulations, your Italian ball level has entered the threshold of the ladder ball. If you want to kick the Italian ball with such unpredictable trajectory when falling, I suggest reducing the pursuit of arc and keeping the football still as much as possible in the control of power explosion and foot method.
Qin Xiong frowned slightly. He didn’t like the fact that football kept still when flying, so the trajectory had a straight line and lacked a sense of change or graceful lines.
But he decided to listen to Fan Jiaer’s suggestion and try one.
Runup supports the body to ensure that it is in a nonrotating state when playing football.
Bang!
Football is like a cannon ball.
The speed of the ball is amazing!
Qin Xiong Van Gaal watched the flight trajectory of the football together. In the course of flying, the football suddenly produced an erratic trajectory when it fell. If it is twice as slow, it will produce an irregular trajectory that snakes in front of the door for a short distance!
Qin Xiong slightly open mouth feel a little surprised.
Maybe when he was a child, he didn’t like straight lines because he didn’t have enough strength. No matter how much strength he played, football was generally consistent with straight lines.
But now his strength is enough to make football produce irregular trajectory in fluid mechanics during flight!
Fan Jiaer laughed at the side. It is precisely because the ball is stationary that the ball is influenced by the streamlined surface air pressure difference and gravity in the process of movement, but not by the air pressure generated by the spin of the ball, so that the erratic line can be generated.

Qin Xiong intends to continue to practice Italian ball. As Fan Jiaer said, he is just an introduction to ladder ball.
First of all, the goal of Italian ball is to shoot the ball into the goal.
Secondly, the flight path of football will encounter two obstacles. The first defensive player physically blocks the second goalkeeper from saving.
Qin Xiong, where he is located, can kick the football out of an irregular trajectory that he is not familiar with. He will take the training first to ensure that the football can hit the goal range, and then control the high accuracy of the football flight trajectory through repeated practice.
This is not a day’s work, and there are no quick shortcuts. You have to train day after day.
But Fan Jiaer interrupted his plan to let him pick up all the football scattered on the court and go with him.
Qin Xiong didn’t ask questions. If he wants to ask what he is doing in front of Fan Jiaer and insists on training here, there must be something wrong with his head.
Fan Jiaer brought Qin Xiong to his office. He sat Qin Xiong in a chair facing the tactical board in front of a tactical board.
Qin Xiong, you have a good basic ability, physical quality, ball skills and excellent team consciousness, but you haven’t fully understood the real professional football, especially the highlevel toplevel games. Come to me after training in the future, and I will help you get to know Dutch football and European football faster.
Qin Xiong smell speech nodded solemnly.
He didn’t get such an opportunity for nothing.
What will Fan Jiaer cultivate himself alone? He doesn’t ask.
He is a very realistic person.
Fan Jiaer must have hoped to improve his strength as soon as possible, so that Qin Xiong might as well pay attention to study hard and grow with the highest efficiency to repay the other party. This is the result that the other party wants to see most.
Fan Jiaer said with a serious face, First of all, you must realize that there is a huge gap between the football you play in the training match and the football you play in the youth league. I don’t mean the gap between players’ strength, but the training match, the youth league and the professional league are in a semistatic state, and the real toplevel competition is mobile!
Qin Xiong frowned slightly and didn’t seem to understand Fan Jiaer dialect very well.
Fan Jiaer drew 433 figures on the tactics board, saying, I mean the semistatic state, which means that the formation position of most teams in your youth league represents the technical and tactical forwards, midfielders and defenders are responsible for their own areas, and each role does its own job. But what about the real toplevel competition? You will see that the strikers change positions with each other, and the midfield frequently inserts the fullback assists to almost the same winger, not to mention that the striker retreats and assists in the midfield. In the process of the game, a player can complete the defense in the fullback defense zone one second, and then organize in the midfield for one second and suddenly insert the striker!
Qin Xiong understood that he nodded at once.
Simply put, the lack of more changes in the youth league is actually limited by the strength of the players, perhaps physical strength, perhaps experience, perhaps teamwork tacit understanding, which is always different from the real top competition.
Fan Jiaer continued, There is no doubt about the status of Dutch football in the world. We have promoted the third revolution of world football skills and tactics. Do you know what is offensive and defensive?
Qin Xiong nodded first and then shook his head.
He is not sure whether he understands correctly.
Fan Jiaer drew some shoulders on the tactics board, and there was a backward arrow at every point, saying, Now many amateurs will abuse the word offensive and defensive. Even Ajax didn’t dare to attack and defend the team when we were training players. You should have noticed that in the mouth of each of our youth coaches, we will say that we will play offensive formation today, but we will never say that we will play offensive and defensive today. Even so, you should remember that the coach asked you to take on defense.
Qin Xiong said that the overall lower back compression changes
These four points are the essence of Ajax’s defensive training. The first point is that every player should participate in defense as a whole, which is the most basic.
Fan Jiaer nodded. Yes, each of our players is required to take part in defense, and we focus on offensive formation, but we won’t say that we are playing offensive and defensive tactics. Do you know anything?
Qin Xiong’s face was puzzled. In fact, this is also the place where he was not sure just now.
Literally speaking, the training requirements of attacking and defending Ajax are already attacking and defending
Fan Jiaer said, If it is considered that all players participate in the offensive and defensive, what is the special merit of creating offensive and defensive tactics in the Netherlands?? Actually, no club in the Netherlands can perfectly implement such skills and tactics, because it requires too many players and needs seven worldclass players to achieve real offensive and defensive. Players need to reach a high level at both ends of offensive and defensive from technical and physical quality to team awareness, and then 11 players can change their roles at will. When you are present, you don’t have to think about where you play in the field. When the game is going on, you are the midfielder. When you have the chance, you go back and defend. When you have the chance, you are the striker! In addition to the goalkeeper, the other player can maintain a balanced offensive and defensive body in the constant change of role position. This is the real offensive and defensive!
Qin Xiong had an instant epiphany.
He can imagine how powerful Fan Jiaer said attack and defense would be. It would be a magnificent sight.
In the midfield, strikers can frequently switch positions, and the strikers can also complete the organization and connection of the midfield. The midfield can also perfectly replace the strikers and score points. Repeated impact at halftime can make opponents lose their marking targets frequently in the dazzling, and then join the defenders to constantly insert lateral transposition and switch the attack direction. This attack is simply impossible to prevent.
But as Fan Jiaer said, there are almost no teams that can really attack and defend.
Not only does a player need to have the adaptability and technical ability of three positions of defender, midfielder and striker, but also needs a player like this and can cooperate perfectly!
