"Let's all analyze this attack, why did it fail?"

In the tactical conference room on the second floor of Southampton, Bielsa pointed casually, and a video appeared on the big screen behind him.

This footage is a scene from Southampton's away game against Chelsea.

Drogba retreated to get the ball in front of him, and with Terry behind him, Drogba had no chance and was forced to pass back.

Pogba ran forward and when he grabbed the ball, he was blocked by Frank Lampard and couldn't pass it forward.

On both flanks, Neymar and Sturridge's sprints forward, both became useless.

After watching the whole process, Bielsa asked Martin Hunt to play it back before Drogba received the ball.

Thus, the whole situation is clear.

Pogba couldn't get the ball out because he needed to run up and catch it.

And the reason why he had to run was because he plugged in too late.

Theoretically, if Pogba had picked up the ball earlier and split up the flanks, Neymar and Sturridge would have been able to pose a lethal threat, while Drogba would have been able to turn around and plug in in the middle.

In this way, the whole attack is completely alive

Drogba was the first to stand up after watching the video.

'I was carrying John Terry with my body and I noticed Neymar and Sturridge, but I couldn't turn around and I had Mikel in front of me, so I had to pass like that.

There are people behind you, and there are people in front of you, so you can only pass diagonally.

Drogba's choice was reasonable.

Pogba also raised his hand and stood up, "I was a little hesitant to plug in because I didn't see the back. ”

In Southampton's tactics, the two central midfielders have the duty and obligation to help the midfielders.

"I've already run over, and I'm not in place yet, but if I run over, it proves that I'm here, and you can press it up."

Nemanja Matic also stood up to defend himself.

Bielsa heard this and nodded, "This is a very regrettable offensive failure, and the reason why I brought it up for discussion is to tell everyone that it is very necessary to maintain good communication and communication."

'If Nemanja Matic and Pogbardo had talked, the latter would have been able to press up, and then there would have been no situation where Lampard had been blocked by Lampard after receiving the ball, and he would have been able to split the two wings in time, which would have been a very threatening attack.

"Let's look at the next one"

With a wave of Bielsa's hand, the big screen immediately moved on to the next topic of discussion, which was also a video from the game.

Yang Huan was standing outside the tactical conference room on the second floor at this time, watching this scene in the conference room.

At Southampton's tactical discussions, the coaching staff will raise a number of issues that anyone can say, expressing their own feelings, what they thought at the time, or what outsiders think.

A football game is at least ninety minutes long, ever-changing, and anyone, all the time, is making mistakes.

If you look at it from the point of view of probability, every attack will encounter the strict destruction and failure of the defense, which is an inevitability.

On the contrary, the offense that can complete the goal and score is successful, but it is a kind of accident

So players make mistakes, and they keep making mistakes.

Even players like Nemanja Matic and Toni Kroos, who have an astonishing pass success rate, are making mistakes.

For example, this player has a better chance, but passes it to another player.

Or maybe you didn't see it, you missed a good pass, and so on.

According to Yang Huan's idea, then all the mistakes and problems will be discussed, and everyone will express their opinions.

At first, the coaching staff was concerned that such a discussion would hurt the atmosphere of unity within the squad.

But after trying it a few times, it works pretty well.

If you have any thoughts and any displeasures, you can say them, and it will be easier to let go.

And there is a good saying, loyalty is contrary to the ear, and the dissatisfaction from teammates may be able to promote the improvement of players.

As for the personality of some players, they can't accept this kind of discussion, but in the general environment, a small number of them can only accept it, and gradually integrate into it and adapt to this atmosphere.

No, Xavi Martinez and Gary Cahill were arguing over an own goal in judgment during a defense, and they quarreled, and even Neuer was involved.

The three of them were arguing in the conference room, their faces were red and their necks were thick.

People who don't know must have thought they were going to fight.

But in reality?

After the quarrel, they high-fived each other, shook hands, and were fine

Yang Huan was very satisfied with this situation, and also liked this atmosphere, nodding and smiling when he looked at it outside.

"Not bad, really good"

"That's what you did at the beginning," Marcus said with a smile.

"Who's to say it isn't? When you proposed to do this, Young Master Huan, everyone had a lot of opinions, but now, we are planning to promote it to the work of our various groups," Howard Hamilton also laughed.

Yang Huan waved his hand, "Okay, okay, don't learn it, specialize in Sun Yue's bastard's sycophantic kung fu."

All three laughed in unison.

"I've heard that the research you did recently has achieved phased results?"

"yes," Marcus O Du Satui nodded.

It is easy to talk when there are results, and if you can't see the results, you will always keep investing, which will hurt the hearts of investors

"Let's hear it," Yang Huan was also quite interested.

The two experts looked at each other and smiled.

"Let's talk about it," Howard Hamilton said, pointing to Marcus O Sado.

The latter nodded, and this was the beginning.

"Eh, don't fix those professional terms, simple and straightforward, I don't understand too profound"

The two of them suddenly became helpless and amused.

"Master Huan, this study we are engaged in, in statistics, is called regression to the mean, and in finance, it is called mean reversion."

"The meaning is very simple, for example, if a player's level is an average of five points, then, when he scores six points in a game, then he has a certain probability of returning to five points in the next game, and there is also a certain probability that he will be higher than six points, but it will definitely not be six points."

"If it is a table to seven, the probability of the next regression to five points is higher, the probability of a score above seven is lower, eight points and nine points are ten, and the probability gradually increases.

"By the same token, if the player is not in good form and the table falls to four points, then he also has a high probability of returning to five points in the next game, and then three points and two points, and gradually increasing."

Yang Huan understood what this meant, "What's the use of this?" ”

Howard Hamilton finally couldn't hold back and interjected with a smile.

"Quite simply, from the point of view of a certain player, we need to analyze his probabilities, from his last game, to predict his next game."

"If we zoom in on this phenomenon and look at the whole team, then we can accurately predict the state of the team."

Yang Huan was full of amazement when he heard this, but he couldn't believe it, "Is this possible?" ”

You know, Redknapp had asked analysts to do that.

But the answer given by analysts in Southampton at the time was that they couldn't

Marcus O Du O Satoy nodded very affirmatively, "Probably, absolutely"

Howard Hamilton also nodded.

"This is not only to examine the number of your own team, but also to analyze the number of opponents, and even to refine to each position, each player, and even the various changes after the dislocation of players in different positions, and then analyze the situation of the team itself, and finally calculate a relatively accurate probability."

"Once we have mastered such an algorithm, we can even predict which player or substitute to use in a certain position in the next game, which combination of players to use, which can maximize the team's probability of winning, and then recommend it to the manager."

Yang Huan was a little dumbfounded when he heard this.

If you can really master this set of invincible algorithms, won't Southampton be invincible in the future?

But when he threw the question out, Marcus O Sadoy and Howard O Hamilton both shook their heads and laughed.

"Young Master Huan, you must know that there will always be only relative in this world, there can be no absolute, we can calculate only the probability, it cannot be one hundred percent."

"Yes," Howard Hamilton also nodded.

"It's like a duel of players on the wing, Neymar vs. Ivanovic, assuming one-on-one, Neymar is 70% sure that he will not concede the ball, but the problem is that every duel is an independent touch of this probability, every time it is 70%, so the probability of conceding the ball is always 30%.

Yang Huan suddenly understood, "It's like rolling the dice, every time you roll it, the probability of how much you shake is the same." ”

'That's right, so the more one-on-one Neymar and Branislavic have in a game, the more likely it is that they will concede goals in theory, and the same applies to attack and defence.

Marcus O Du O Satoy nodded incessantly.

"Therefore, we can only calculate a probability forever, there is no 100% victory, and as long as there is a probability of saving, there will always be a small probability of things, what we can do is to use this set of algorithms to reduce the occurrence of small probability events as much as possible, as far as possible to ensure that nothing goes wrong."

This is Murphy's Law.

If you're worried about the birth of something, then it's likely to happen.

Therefore, on the football field, it is never possible to eliminate the emergence of a small probability of upset.

Although Yang Huan couldn't help but be a little disappointed that there was no absolute certainty of winning, after all, everyone wants their team to win forever.

But if you can always keep your team in a good position to win, or if you know exactly how to beat your opponent every game, then it's worth the research

Besides, as long as Southampton's strength is strong enough, and with such a set of algorithms and analysis, let's ask, in professional football, which team is worth fearing?

The whole of European football, is not yet allowed to run at Southampton?

"I understand," Yang Huan nodded approvingly.

"Both, don't hesitate to continue your research, it's very useful to us, whatever you need, just mention it, I will fully cooperate"

Marcus O Du O Satoy and Howard O Hamilton were still worried that Young Master Huan would be a little disappointed just now.

Unexpectedly, Yang Huan would give them such strong support again, and he was immediately overjoyed.

After sending away the powerhouses in the double-digit field, Yang Huan didn't bother the coaching staff and players who were meeting inside, and walked to the lounge by himself.

The Little Prince of Qatar, who has just started playing Clash of Clans, is now completely fascinated by the game.

If it's just him, that's it.

He also brought in a group of friends and formed a Hamad tribe by himself, which is full of local tyrant players who treat money like dung and spend money like running water.

Yang Huan had just walked outside the door of the lounge when he heard a triumphant shout from inside.

"Wow Ka Ka, it's so enjoyable, I dropped a gooseberry rick, haha, see if they Uncle Sam dare to come to our Middle East to spread wild in the future, it's enjoyable, it's too enjoyable"

That voice, that momentum, not to mention how violent it is
