Sun Tzu has a cloud in the art of war, knows himself and knows his opponent, and will not be defeated in a hundred battles.

The same applies to professional football, which is known as a war without gunpowder.

Before each game, the head coach will fully understand and study both sides of the opponent, and then find out the opponent's strengths and weaknesses, defend against the advantages, and use the weaknesses to attack.

So, to a certain extent, before a professional football match, the head coach has a certain psychological preparation for the outcome of the game, and even, for some experienced coaches, when the schedule comes out, they already have a detailed overall plan for the trend of the whole season.

Which games to do their best to fight for three points, which games to get a point to qualify, and which games to lose are acceptable, these are all in the manager's season plan.

But the problem is that the season is so long, players will inevitably have injuries, there will be ups and downs in form, and the team may have special situations of one kind or another, which will affect the team's combat effectiveness, and then lead to mistakes in the team.

This brings us to the issue of fault tolerance.

Generally speaking, the stronger the overall strength of the team, the more stable the tactical system, and the higher the tolerance rate.

It's like Pep Guardiola, don't look at his record at Bayern Munich is not very ideal, but if you carefully study his coaching results, it is not difficult to find that his results in coaching Bayern are very stable, and the games that should be won are basically won.

In other words, Pep Guardiola's coaching is characterized by a high margin for error.

On the other hand, Manuel Pellegrini's Manchester City has a very low margin for error, and frequently drops points in some games that should have been won, or even easily won, which is indeed quite undeserved, and it is also the reason for Manchester City's poor performance in the league this season.

Of course, no matter which manager it is, it is impossible to be foolproof, and there will always be times when you miss.

The more you are in that kind of game, the more likely you are to make mistakes, and the easier it is to make mistakes and lose.

That's why the Champions League knockout matchups are so fascinating!

After Inter Milan beat Juventus 3-0 away and won the Serie A title in the new season two rounds ahead of schedule, all! Nerazzurri fans are calling for a push to get ahead and get an upset win over Southampton.

But hope is hope, and reality is always cruel.

As Jurgen Klopp had anticipated before the game, Carlo Ancelotti continued to feature a substitute in the FA Cup semi-finals in order to play the main role in the first leg of the Champions League semi-final.

And Inter Milan, although they have just played a tough game with Juventus, still played their main role in midweek.

The difference is that although Ancelotti is playing away, he is mainly attacking, and Inter Milan is playing at home, but Klopp's tactics are mainly to contain the Saints' attack.

All of Europe knows that no team can beat the Saints.

Inter Milan itself is at a certain disadvantage, if it really fights against the Saints, isn't it lighting in the toilet and looking for death?

The Nerazzurri were clearly well prepared for the game, with Jurgen Klopp's side doing well in terms of defence and pressing, especially in Klopp's specialisation of lateral cutting, which cut off the Saints' passing lanes.

This also made it difficult for the Saints to create a dangerous attack throughout the game.

Seventy minutes have passed before you know it, but neither side has made substitutions, and the intentions of the managers of both sides are already obvious, that is......

…………

…………

"They're all gambling!"

Messi raised his head, looked at the dazzling lights over Milan's Glory Stadium, squinted his eyes, and the thought flashed through his mind.

The quality of both sides was excellent, Ancelotti chose to attack, Klopp chose to defend, the tactics of both sides were also very targeted, and the players did not make big mistakes in terms of execution.

That's why it's still 0-0 so far.

As for why there are no substitutions, it is not difficult to understand.

Inter Milan did not dare to change.

Because Klopp knows very well that this is already the strongest lineup he can put out at the moment, and it is not easy to find the rhythm of defending Southampton's attack.

As for Southampton, it's not hard to see why.

Carlo Ancelotti said before the game that a draw away is acceptable, and the home team will do their best to win.

But he also said that Inter Milan had just beaten Juventus three days ago, and the physical consumption was very high, coupled with Klopp's tactical characteristics, the physical requirements were very high, so the team would concentrate on the last ten minutes.

He must have planned a replacement by now!

Messi turned his head sideways and glanced at Carlo Ancelotti, who was standing on the sidelines.

The Italian fat man was talking to his assistant coach in an ear, and his teammates on the bench behind him began to jump stupidly.

These are all signals to change people!

But Messi does not intend to wait for the manager's substitutions.

He wanted to go the extra mile.

"Danilo!" Messi made a gesture towards his teammate Danilo on the right.

Although the two have only been together for one season in Southampton, because Messi and Alves have a tacit understanding in Barcelona before, the tacit understanding with Danilo has also been established quickly in Southampton.

With a gesture from the Argentine, Danilo knew Messi's intentions.

Southampton soon launched an attack down the left, with Eden Hazard and David Alaba picking up the ball on the left to draw the attention of Inter's defence.

Due to the individual quality of the Saints' players, especially Eden Hazard and David Alaba, who are both top players in their positions, Inter Milan's defensive players also take it very seriously, investing heavily on the left side of the defence.

Not to mention, Inter Milan's defense was really tenacious, even with similar physical exertion, they still managed to block the Saints' attack on the left, and through team defense, the Saints had to pass the ball back to the backline.

It is said that it is the back line, but in fact, Varane and Laporte have already pressed to the halfway.

As soon as Laporte received the ball, he immediately passed it to Varane.

Varane received the ball head-on, stopped, looked up, and saw Messi running back, Danilo pressing forward on the right side.

After working with each other for a season, Varane naturally knew the intentions of Messi and Danilo, and passed the ball directly to Messi.

The Argentine's retreat caused a lot of problems for Inter Milan's defence.

To follow, or not to follow, this is a difficult question!

But this time, the timing was not good, as soon as Messi got the ball, Pjanic posted it, which caused Messi to be entangled directly by Pjanic after receiving the ball.

But Messi is Messi in the end, even if he was entangled by Pjanic, he quickly used his personal ability to create a gap, directly shook off Pjanic, and passed the ball to the big penalty area.

But because of the pestering of Pjanic, the timing was missed, and both De Vrij and Juan Jr. returned to position in time.

When Messi's pass came to the front of the penalty area, De Vrij suddenly stepped up and grabbed ahead of Suarez, and cleared the ball directly with one kick.

Inter Milan has defused the crisis again!

Messi couldn't help but feel a little stupid when he saw that the first cooperation didn't work, but when he looked at Danilo, his eyes revealed a firmness.

Dude, look for a chance, let's come again!

Okay!

The two looked at each other and returned to their places.

With the cooperation just now, the Southampton players also clearly understood Messi's thoughts, and they all began to actively cooperate with Messi.

This is not because Messi has any special treatment in the team, but because this kind of attacking routine that suddenly plays from one side to the other side is what Southampton is good at.

Choosing to support Messi now is just a matter of taking advantage of the situation.

Ancelotti, the manager on the sidelines, also realized that this could be an opportunity, so the idea of making a substitution was decided to be put down for the time being, and then we will see.

So, the whole team had this idea, and when they held the ball again, they still launched an attack from the left side.

Eden Hazard, David Alaba and Angel Di Maria were not only trying to break down Inter's defence when they picked up the ball on the left, but they were also drawing Inter's defensive attention, so the attack was more focused.

Inter Milan also felt the pressure from the left side of the Saints and began to adjust their defensive focus to their right side.

Darmian, Khedira and even Pierre-Emerick Aubameyang up front were aggressively dropping back to defend.

The Nerazzurri's defence was not a fuel-efficient lamp either, and with the concerted efforts of the players, the Saints were once again able to contain the Saints' attack down the left.

David Alaba saw that there was no chance and passed the ball back to Toni Kroos again.

The German midfielder glanced at the ball out of the corner of his eye before receiving the ball, Messi retreated again, and Danilo went up.

What's more, as soon as Messi retreated, Alex Sandro did not follow.

With that in mind, Toni Kroos quickly passed the ball out.

The ball quickly came to Messi's feet, Tony Kroos's pass was wonderful, Messi stopped, turned around, and the whole process was completed very comfortably and very smoothly.

Because when Messi received Tony Kroos' pass, he already knew that there was no opponent around him.

And Messi turned around and immediately started and dribbled forward.

At this time, Alex Sandro realized the problem and immediately wanted to rush to Messi, and Pjanic also abandoned Pogba for the first time and rushed to Messi.

In the process of dribbling the ball at high speed, Messi still watched and listened to all directions, and as soon as the opponent moved, he immediately followed suit, and directly passed the ball diagonally to the back of Alex Sandro.

Danilo is like a dormant cheetah on the right side, and when he sees Messi passing, he is like a sharp arrow off the string and sprints out.

In the Inter Milan penalty area, Suarez also had a tacit understanding to run forward, ready to meet Danilo at any time.

De Vrij and Juan Jr. are also close enemies, following Suarez every step of the way.

Everyone knows that it would be dangerous to let the Uruguayans get the ball in the big box.

But what no one expected was that Danilo temporarily changed his attention, because he saw that Suarez was difficult to receive the ball under the opponent's key marking, and at the same time, he also saw Pogba raise his hand to ask for the ball at the edge of the penalty area.

In this position, in this area, the French midfielder is a play on the spot.

So, Danilo quickly crossed the ball.

The ball was almost along the white line at the edge of the penalty area, from right to middle.

Messi was sprinting, but he didn't intercept the pass halfway, so the ball came smoothly to the top of the arc of the penalty area.

Pogba faced the incoming ball, stopped, accurately heard the direction and position of the ball he wanted it to go, and then picked up his right foot, and directly volleyed against the ball.

A bang was heard at the scene, and the ball was like a cannonball coming out of its disembowel, and it went straight to the left side of the goal with lightning speed.

In the penalty area, De Vrij made a flying sliding tackle to block the shot, goalkeeper Handanovic struggled to make a flying save, trying to save the ball, and even right-back Darmian was desperately rushing to the goal......

But it was too late!
