This made Jiang Tian feel extremely surprised!

You must know that in terms of player physical training, Jiang Tian has extremely rich training experience, he has a deep understanding of the physical limits of players, and often can also grasp the proportions of training well.

Before Gao Feng fainted when he was climbing the mountain, including the loss of strength of the other players in the back, in fact, it was all in Jiang Tian's plan and control, and now Gao Feng's team members have appeared on the training ground again after the recuperation of those physiotherapists and team doctors he found, and their physical fitness and state have also been improved in a short time, which shows that Jiang Tian's extreme physical training method is still quite effective.

It's just that Jiang Tian has never been able to see Duan Yun's physical limit.

In the first few days, Jiang Tian did feel that the high-intensity training had made him visibly tired.

But in the next few days, Duan Yun showed his extremely strong physical recovery ability.

It seems that it only takes a few hours of sleep for Duan Yun to completely 'resurrect with full blood', and his performance is getting better and better day by day.

In the internal sprint and middle-distance running tests, Duan Yun has always maintained the first place in the team, and what shocked Jiang Tian was that Duan Yun's running performance was even close to the current international track and field world record, so much so that he thought that there was a problem with his stopwatch several times, and changed the watch three times in four days!

And judging from the situation of the intra-team confrontation in the past few days, Duan Yun's performance is also very eye-catching, the shooting accuracy is extremely high, and the dribbling skills are also quite good, basically as long as the ball is under his feet, it is difficult for other players to snatch it back, and it often takes two or even three or four people to assist in defense, it is possible to block Duan Yun's dribbling, but it is still impossible to prevent Duan Yun and other players from passing and cooperating with each other.

The warm-up games in the team are basically divided into two teams by the main players and substitute players, and Duan Yun is the first time to be selected for the national team, so he is naturally on the side of the substitute team.

It stands to reason that there is still a gap between the substitute players and the starting main players of the national football team in terms of strength, and the warm-up matches often end in the main team winning by a large score, but this time with the addition of Duan Yun, this situation has been greatly reversed.

Originally, Jiang Tian wanted Duan Yun to play the back position, after all, Duan Yun's speed is fast and his physical strength is extremely strong, and when the national team used to play against East Asian teams, because he was often on the defensive, his teammates had too much physical exertion, and often the defense was the first to collapse, so Duan Yun was arranged in the back waist position to strengthen the durability of the team's defense.

But through the games in the past few days, Jiang Tian found that the position of using Duan Yun to kick the back waist was obviously a bit 'condescending'.

The strikers are undoubtedly some of the best players in the team, and this is no exception in the national team.

Gao Feng and the other two wingers have been selected for the national team for three or four consecutive years, and they have also had a few good performances in previous years' competitions, and their strength is unquestionable, and they no longer need to prove themselves.

However, in the warm-up games of the team in recent days, the most points are just outstanding, only eighteen-year-old Duan Yun, although Jiang Tian arranged a defensive task for him, but in fact he has a huge range of activities on the field, covering almost the entire midfield, in addition to completing the defensive tasks arranged by Jiang Tian for him, but also often involved in the attack, and even several times Duan Yun traveled long distances, from the backfield with the ball through several people, and finally scored a wonderful moment.

In addition, Duan Yun has an even more amazing killer feature, that is, the free kick 'heavy artillery'.

If dribbling and shooting skills can be improved through training, then Duan Yun's free-kick 'heavy artillery' stunt is a complete talent.

In the past, there was such a 'demon' in international football, this player was not tall, but his thighs lacked surprisingly thick, even thicker than the waist of some adults.

If a player wants to kick a powerful 'heavy artillery', in addition to his skills, the most important thing is the explosiveness of his legs.

That 'demon' is relying on the explosiveness generated by his thick legs that is far beyond ordinary people, and can often kick some incredible classic free kicks in the tournament to score goals.

The force and speed of the ball he kicked are amazing, so that there are often human walls and when eye-catching players are smashed by the ball he kicks, they fall directly to the ground and pass their breath, although it will not kill anyone, but the feeling of being hit by a hammer is not something that ordinary people can endure!

Even the most exaggerated time, although his angry shot was saved by the goalkeeper, the goalkeeper paid the serious consequences of a fractured wrist in his left hand, which shows how terrifying the power of the shot is at this time!

And now, in Jiang Tian's opinion, Duan Yun also has the ability to kick out the 'heavy artillery', and compared to the 'demon' in international football back then, it is even better!

Although the football demon back then had hard feet and strong explosiveness, his accurate head was not very good, and he has been the main defender for many years, which in itself can also explain some problems.

But Duan Yun's shot was very accurate!

He can even start just past midfield, and no matter how arc the ball is in mid-air, it will eventually fly into the frame of the goal!

Even during the warm-up match, there was such a small episode, when Duan Yun was instructed by Jiang Tian to take a free kick 30 meters away from the goal, when a player defending in the penalty area tried to block Duan Yun's shot with a header, the ball directly knocked him unconscious, causing a burst of nervousness and restlessness on the court!

Being knocked unconscious by a free-kick has never been seen before in a football match!

In fact, those veteran players didn't pay attention to this player who broke the record of being selected for the national team at first, but after more than ten days of training, the arrogance and superiority that these veteran players had in the face of Duan Yun before were gone.

Everyone saw that Duan Yun's strength was above them, and it was only out of self-esteem that these people did not say it.

However, Duan Yun has shown more and more 'dominance' in the team, as a substitute defender in the training match, Duan Yun not only defensively, but also began to organize the team's offensive, through a variety of amazing passes and assists, while scoring his own goals, he also repeatedly helped other strikers score.

In the last few days of the training camp, the youngest Duan Yun had even begun to shout on the court to command the old players of the whole team, and he was completely full of the momentum of a 'field commander'.

It is simply an unbelievable thing for a newcomer to be able to point fingers at the old players of the entire team, which also shows that Duan Yun's ball skills and overall view on the court have indeed won the recognition and convincing of other players!

And after observing Duan Yun these days, Jiang Tian finally made a major adjustment, and arranged Duan Yun to the midfield position of the main team, replacing the veteran captain Chen Jianguo, who has been selected for the national football team for six consecutive years!
