(a)

This substitution, which was also carefully arranged by the Hamburg coaching staff, was still designed for the core offensive drill of the two liberos.

After Pietroipa's departure, Ruud van Nistelrooy stepped into Pitt's lone arrow position and the opposing player became Hoffenheim's centre-back. Right wing-back Tescher replaces Ruud van Nistelrooy and battles for the ball at the top of the penalty area and pins down the opposition midfield. Left wing-back Ze Roberto moved to Teshe's position, giving up his left midfielder position to the new South Korean youngster.

Although Hoffenheim uses zone defense, unlike the hand-to-man defense, which is chaotic due to the dazzling substitutions and changes of opposing defensive players, this kind of one-time substitution brings multiple position linkage changes, and for Hoffenheim, there will still be a short period of discomfort.

(b)

There are several changes in the attacking routine adjusted by the Hamburg coaching staff, after Ze Roberto moved from the left wing-back to the right midfield, the Hamburg team's attack on Ze Roberto's source of gravity shifted to the right.

Compared with Teshe, Son Heungmin's header is weak but he is good at dribbling, breaking and speed, and his characteristics are more like Elia, so after this adjustment, Ze Roberto's pass is not only handed over to the middle of the road Tescher's header ferry, but also has an oblique pass to the left for Son Heungmin to use his speed to go straight to the bottom.

Similarly, Ruud van Nistelrooy went from personally participating in the passing link of the attack to involving and suppressing the opposing central defenders, and Ruud vanney's involvement and suppression was bound to make Hoffenheim's two central defenders feel the pressure more than Pietroipa.

The top of the arc of the big penalty area acts as a cannon rack, and the ball path of the ferry is two more points, in addition to knocking back to Chen Zhuo's long-range shot, there is also a ferry to the left side to Sun Xingmin, and directly handing the ball to Vanney.

In this attacking routine, Son Heung-min and Tescher are both substitutes, with Elia and Berg in the regular line-up, and the right midfielder is choosing between Ze Roberto and Trokhovski.

Compared with the tactics of Van Nistelrooy suppressing Hoffenheim's midfielders as a passing hub in the first half, Hamburg's adjusted routine also has advantages and disadvantages. Of course, the Hamburg team has a lot of offensive means, but whether it is Tescher or Berg, their competition for the first landing point and the pressure on Hoffenheim's midfield, there will still be a certain gap compared with Vanney.

In the first half, Ruud van Nistelrooy almost single-handedly suppressed the opponent's double midfield, and after the position adjustment, Gustavo alone was enough!

Without waiting for coach Rangnick to give instructions, Hoffenheim's captain Salihovic made corresponding deployment adjustments according to the opponent's position.

Weiss stepped forward to defend Chen Zhuo, and the midfield was adjusted to a diamond-shaped position.

Eduardo returned to the left midfield to form a confrontation with his Brazilian predecessor Ze Roberto, which had a direct impact on the Hamburg team's attacking provenance.

Striker Obasi, who had switched to the left wing-back position at the back of the first half, did not immediately push into the forward position, and Eduardo signaled him to cooperate with him in defence to press for Ze Roberto.

Salihovic's attitude is clear, they not only want to affect the attacking source of the Hamburg team, but also are ready to make full use of Ze Roberto's physical and speed shortcomings, and make him a "soft underbelly"!

(iv)

After Ze Roberto's attacking source came under more pressure, Hamburg were quick to adjust.

In the first half, against Savichovic's defensive style of pressing and active fighting, Ze Roberto spent more time on one look, two and three passes, which is also in line with his age and jishu style.

After being forced by Eduardo and Obasi in the second half, Ze Roberto used more one-foot passing, and even gave up the ball and transfer altogether, and instead used running to involve and suppress the positions of the two Hoffenheim players to create opportunities for his teammates.

As for Chen Zhuo, he also began to take the initiative to retreat to get the ball, replacing Ze Roberto, and became the source of the Hamburg team's attack, and the attacks on the three points of Teshe, Son Heung-min and Vanney are now more directly launched from Chen Zhuo's back position or even a little further back than the back waist.

Even in a diamond position, Weiss could not completely get out of his defensive area, and although Tescher replaced Ruud van Nistelrooy, his position was significantly lower than that of Vanney in the first half, between Gustavo and Weiss in the diamond position.

Terscher's choice of position and the forward and backward running position made Hoffenheim's double back suddenly appear that Gustavo stood in front to leave space for Vanney, and suddenly Weiss stood behind, which allowed Chen Zhuo to calmly dribble forward.

Hoffenheim coach Rangnick felt that the Hamburg team had obviously put a lot of effort into Hoffenheim's double back parallel position and diamond position, and it was just an adjustment of one player, and the players of the Hamburg team played such a rich cooperation according to the position and running position, which fully shows that the Hamburg team is also a team with high tactical literacy!

(5)

Not only is the tactical literacy extremely high, but the Hamburg team is also very targeted! It was Fulham assistant coach Lelivinson in the stands who felt more and more strongly that the Hamburg team was using Hoffenheim as a "sparring partner" today, doing offensive routines for the regional defense system of the parallel position of the two central defenders!

In the 15th minute of the second half of the game, Son Heung-min did not go down after receiving Chen Zhuo's backfield pass, but chose to cut horizontally......

The camera in Lelivinson's hand tracked Chen Zhuo with another explosive sudden start, and Hoffenheim striker Ibisevic next to Chen Zhuo was thrown out of position by the Chinese player in two or three steps!

"The left midfielder cut inside and forced the back of the diamond position to recover, and then it was a return pass...... "Lelivinson was keen to judge the Hamburg team's attacking line.

As expected, Son Heung-min cut inside and crossed the boccia ball to Teshe, which was knocked back directly by Teshe without pausing, due to Weiss's recovery and Ibisevic's sudden start to throw away, Chen Zhuo, who received the ball, approached the "35-meter" area with a trip......

For Chen Zhuo, it is a bit abrupt to meet the ball without pausing to shoot, such a distance, the goalkeeper's reaction speed is enough, and he can't pin his hopes on the opponent's mistakes, and the tactics do not rely on Meng to complete the attack.

After a kick, Hoffenheim's defender Gustavo was already on Chen Zhuo's shooting line, blocking the angle of Chen Zhuo's foot, and Hoffenheim's players reacted very quickly!

There was no chance to get up, Chen Zhuo took the initiative to cross the horizontal belt on the side, and Gustavo looked at the Hamburg players who did not have a back row in the middle to cooperate, and always followed the movement under his feet, so that Chen Zhuo did not have room to change direction and break through.

"Didn't you take a long-range shot after receiving the return pass, and dribble to the right when there was no angle in the front, was this to open up space for the players who were plugged in in the back row? I don't see who will start from this open space for the time being......" Lelivinson continued his tracking, thinking that Fulham's midfielder also has the ability to quickly fill in the defense.

(f)

Ze Roberto ran behind Chen Zhuo, and Gustavo and Eduardo also exchanged defenses, and Gustavo no longer followed Chen Zhuo to the side, but instead marked Ze Roberto.

For Chen Zhuo, who moved to the right side, this defensive area was in charge of Eduardo, and Obasi cooperated to try to force and block, and behind Eduardo, Christian was already in good standby......

Almost at the moment when Chen Zhuo and Ze Roberto completed the cross-switching, Chen Zhuo passed the ball with his foot! Half-turn in the middle of a lateral run and a straight ball into the defensive area of Hoffenheim's left-back Christian...... The straight-plug diagonal running tactic in the cross-cut is a typical routine when the zone defense tactical system launches an attack!

Hoffenheim's shortcomings are so similar to Fulham's, Hoffenheim's left-back Christian is a 32-year-old Brazilian veteran, Fulham's left-back...... In the next game against Hamburg, Koncheski accumulated yellow cards and was suspended, and it will be substituted for Koncheski who will be substitute right-back Panthill, or Norwegian left-back Björn Ritse, who has been transferred from the Norwegian league this season......

In other words, the offensive tactics of the Hamburg team have also fully taken into account the defensive area of the opponent's left wingback!

Chen Zhuo's pass was very penetrating, and Sun Xingmin's change of direction was also very well grasped, not offside, it was a good ball, and the linesman ignored the Hoffenheim defender's gesture.

After a series of cooperation, South Korean teenager Son Heung-min received Chen Zhuo's through ball on the right side and rushed along the right side!

Chen Zhuo under the tracking of Leliwenson's camera, the running route at this time is also on the right side, behind Sun Xingmin, Leliwenson is puzzled while following Chen Zhuo while shooting, at this time, even if this Chinese player does not go to the middle to do the running position to grab the point to respond, he should be ambushed at the top of the arc of the big penalty area to prepare to grab the second drop point to make up the shot, and run to the side, doesn't that lead to the overlap of positions?
