This goal is actually the embodiment of the experience of Evergrande players, when the weather of the game changes, how to adapt to the weather, and make good use of the weather is actually a science. Pen & Fun & Pavilion www.biquge.info

In modern football, there is a subject called football meteorology, which belongs to a branch of sports climatology, and many sports colleges in Europe have formal credits for studying football.

In football matches, after the study of sports climatology, some experts have put forward the "five differences in meteorology", including time difference, pressure difference, wind difference, temperature difference and humidity difference, and in special cases, "seasonal difference". For the much-talked-about sport of football, these factors have a huge impact.

For example, jet lag, a natural reaction caused by fluctuations in the body's biological clock, can lead to a sharp decline in the quality of sleep, diet and exercise of players. For example, the Barcelona team after the Beijing Olympics had a bad start, and Guardiola believes that this is caused by Messi and other players who participated in the Olympics not being able to adjust to the jet lag after returning to Spain, and the differences in the performance of the national teams and clubs of major stars, as well as the famous "World Cup syndrome", are all related to jet lag. The average player's way to deal with jet lag is to sleep and reverse the training time, which should be done in advance, but frequent repetition can also damage the player's physiology.

For example, the pressure difference factor also has a very large impact on the football game. For example, the 13th World Cup was held in Mexico, which is located in the highlands, and only 132 goals were scored in all 52 games, an average of 2.54 goals per game, the fewest in the history of the World Cup. This is not unrelated to the low air pressure on the plateau. Because under low atmospheric pressure, the athlete's running ability and shooting power are significantly weakened. In order to avoid the problem of pressure difference, since the 30s of the last century, many countries have chosen to train in places with low oxygen on the plateau, but due to geographical restrictions (some countries do not have plateaus), Western scientists have created the HILO plateau simulation training method, that is, low-pressure oxygen chamber training. This method can enhance the antioxidant capacity of skeletal muscles, and the effect is even better than traditional altitude training. This kind of simulation training has become common in European football, and the Spanish media have dug up the secret of Raul's installation of a high-altitude low-pressure oxygen chamber at home, and Raul's game performance is also very related to this high-end physiotherapy equipment.

At the same time, as some experienced coaches, on the basis of understanding the opponent, they must always carefully analyze the local weather and climate, conduct targeted training, and formulate technical and tactical plans to adapt to the local weather and climate before the game, so as to win the game.

For example, in cold weather, the ground will be frozen very hard, the ground will lose its cushioning force, if you accidentally fall in the process of kicking the ball, it is easy to cause fractures, and at the same time, the player's body is relatively stiff, the technical action is not easy to control, and the bones are relatively fragile. During the game, players will be asked to run as hard as possible and dribble the ball less. For example, the 8th Toyota Cup, which is the Club World Cup in later generations, because of heavy snow, according to statistics, the players on both sides fell more than 180 heels in the whole game, and each player fell more than 8 heels on average. One player fell 5 meters away, kicked the ball harder than usual in the snow, and at 11 minutes in the first half, a defender passed the ball from the back and kicked a new ball out.

For example, when the weather is hot, because the ground temperature is higher, in this case, the kicker will feel difficult to breathe, weak legs and feet, and it is easy to cause heat stroke, so it is best to wait until 5 o'clock in the afternoon to play football in the hot summer, and the strong exposure of sunlight will make people feel more relaxed in the process of kicking football. If you play in such a situation, you should always be hydrated. Because during the running, the body temperature of athletes often rises to about 40C. Due to the high ambient temperature, heat can only be dissipated through sweating. If the amount of sweat reaches 1-5% of body weight, the athlete's maximum oxygen intake and muscle work capacity will be reduced by 30-50%, and if the water is not replenished in time, heat stroke and fainting will occur. In addition, in order to dissipate heat, a large amount of blood flows to the surface of the human body, making the person's face red, and the skin is also full of blood, so that the central circulation blood is reduced, causing fatigue of the central nervous system and a significant decrease in muscle activity. At the same time, too much sodium chloride, calcium, potassium, magnesium and other elements excreted with sweat are also prone to cause cramps.

If it is a windy day, the east wind blows, the ball slopes to the west, the west wind signal drifts eastward, the headwind signal falls near, and the downwind ball falls far away. The wind direction and speed are unpredictable, and players can only judge based on practical experience. In the first round of the 1998 World Cup in France, the wind strength in the field was around 4-5. In the first half of the match between Paraguay and Bulgaria, Paraguay had a "headwind", the wind speed weakened the speed of the ball, and also made the players run at a reduced speed, breathing discomfort, and there were almost no decent shots on goal throughout the first half. In the second half, the Bulgarian team took advantage of the wind to attack aggressively, and in the second half, the Bulgarian team defended with all its strength in the "headwind", while the Paraguayan team attacked with all its might. Both teams played a good half-court in the "tailwind".

If it is a sunny day, the impact of the sun on the players on both sides is also very large, so at the beginning of the game, when the two teams choose sides, the captains of both sides will consider the situation of the sun shining on the players' eyes and make a certain choice. For example, many goalkeepers will have a big problem saving the ball when facing the sun, and it is necessary to prepare a hat for the goalkeeper before the game.

On rainy days, due to the resistance of the water, the direction, speed, and landing point of the football are very different from those on a sunny day. Some shots are undoubtedly scored in normal weather, but due to the resistance of the rain, the speed of the ball is drastically reduced, and it is easy to be saved by the opponent. However, the surface of the "water polo" is slippery, and the goalkeeper is prone to getting out of his hands when making a save, which creates an opportunity for the attacking team to make up for the attack.

So when playing in the rain, the tactical idea of the "power" team is to try to kick the ball near the opponent's penalty area. Taking advantage of his height and strength, he used the tactics of long pass and hanging, making full use of the gaps between the wings, and attacking the goal after crossing from the side or hanging diagonally. Or the defender is near the penalty area, receives the ball in front of the goal, and makes a long shot, a header or a second attack. When defending, zone defense is mostly used, with frontcourt players actively blocking and grabbing, and defenders protecting each other. When there was chaos in front of the goal, he was decisive and cleared.

The basic tactical idea of a "technical" team is to keep the ball at their feet as much as possible. Taking advantage of the characteristics of low center of gravity, good flexibility, strong ball control ability at the feet and accustomed to "water warfare", he insists on playing ground ball and offensive football. When the rain is light or the rain stops, the turf friction decreases, the ball speed and the rebound speed of the ball increases, so whenever you have the opportunity, you can shoot decisively with your feet, and the frontcourt players will insert the supplementary shot. The grass is muddy and waterlogged, and the ball is easy to stick and not move halfway, which has a great impact on the skills of passing, receiving, leading, and passing. Therefore, players must react to each other at all times and actively counter-attack once they concede a goal. Defend intensively around the penalty area.

As a veteran, and a veteran of high-level professional leagues such as Serie A and the Premier League for a long time, when the young players of the Longteng team were still slowly adjusting on the field to adapt to the rainy weather, high-level players such as Diamanti immediately began to take advantage of the change in the weather to make changes, and the change in the way he played also changed the score on the field.

That's the difference between a high-level, experienced player and a young player with no experience, and it's also a reflection of the golf quotient.

After the goal, Guangzhou Evergrande immediately changed the situation on the field, because the team's momentum had risen.

At this time, under Zhang Sheng's reminder, the players of the Longteng team began to make tactical changes on the field, and began to use the slippery field to play the pass under their feet faster, but at this time, the Longteng team encountered another problem - lack of physical fitness.

After nearly 80 minutes of play, the players of the Dragon Teng team, who are not used to experiencing this kind of high-intensity game, are still a little out of rhythm in terms of physical fitness. Especially Lin Feng in the midfield, after running up and down for most of the game, his physical strength was exhausted, and Zhang Sheng had to replace him with Tao Wentao.

After Tao Wentao came on the field, the Longteng team could only temporarily retreat comprehensively, after all, the young player and the team had relatively little cooperation. If it's just defense, it's okay to say, with other players shouting, he can still play accurately. In terms of offense, because of the lack of skill, he can't play the suddenness required by football offensive tactics at all, although Tao Wentao is not worse than Lin Feng in terms of foot skills or passing and receiving ability, and even in terms of technology, he should be stronger than Lin Feng, but the experience of the game is far inferior to Lin Feng, and his performance is not as good as Lin Feng.

After replacing Lin Feng, Zhang Sheng continued to make substitutions to enhance his defensive ability, that is, he replaced Shu Jun with Xiao Yunfan, as the captain on the field, Shu Jun ran a lot in order to set an example for the players, and at this time, his physical fitness could not keep up with the rhythm of the game.

After Shu Jun got off the field, the captain's armband was handed over to Wen Kai, as the oldest and longest-serving player on the field, Wen Kai was the best choice for the team's captain on the field.

After the departure of Deng Chaoqun, the first captain of this season, and the third captain of last season, has not been decided, several captains of the team have also been appointed. Last season's second captain Shu Jun won the captaincy position with absolute prestige, and in addition to Shu Jun, Wen Kai, who served the longest, won the second captain's position. As for the third captain, in order to show his attention to Lin Feng, Zhang Sheng handed over this position to him, which is also a reward for Lin Feng not leaving the team after last season, of course, with Lin Feng's qualifications and performance, he did not live up to Zhang Sheng's expectations.
