The coach was at a loss

教练不知所措

He had tried everything that he could to ensure that his right-back never strayed further than 12 metres from the centre-back but the player could not take in the information

他已经尽力确保右后卫离中后卫的距离不超过12米,但球员无法接受这些信息。

The two defenders were even training with a rubber band between them, but the gap continued to open up in games, and opponents succeeded in exploiting it

两位后卫甚至在训练时都用橡皮筋训练,但差距在比赛中不断扩大,对手成功地利用了后者

"Nothing worked," Ruben Saavedra tells

“没事,”鲁宾·萨维德拉(Ruben Saavedra)告诉他

"Even when the player was shown videos, he would challenge the coach and disagree that he was over 12 metres away." That changed when Saavedra used tracking data to prove the point

“即使向球员显示了视频,他也会挑战教练,并且不同意他在12米之外。”当Saavedra使用跟踪数据证明这一点时,情况发生了变化

"We automated a visualisation - a line with the distance showing九游平台

“我们实现了可视化的自动化-一条线显示了距离九游平台

If it was more than 12 metres, that line was red and he could see it

如果超过12米,那条线是红色的,他可以看到

The coach told me, "Now, there is no dispute

教练告诉我,“现在,没有争议

I told you 12 metres and here you are, 12.2 metres." He could no longer argue." How about the example of the analyst at a top European club who was charged with manually recording the position of his team"s players during every throw-in situation九游平台

我告诉过你12米,这里就是12.2米。”他再也不能争论了。“一家欧洲顶级俱乐部的分析师的例子如何?他负责在每次掷界外球的情况下手动记录球队队员的位置九游平台

"This analyst had to identify every throw-in and watch every clip

“这位分析师必须找出每个掷界外球并观看每个片段

The coach had a specific way he wanted them to react

教练有一种特定的方式,他希望他们做出反应

The analyst was having to decide - by eye - the positions of the players and select the ones that were positive and negative to feedback to the coach

分析人员必须通过肉眼确定球员的位置,并选择对教练有正面和负面影响的人

"Now he has a button that he can click for throw-ins

“现在他有一个按钮,可以单击以掷界外球

Within a minute, he can see every single one

一分钟之内,他可以看到每一个

If he sees a yellow square between the positions of the defenders, it means they did it right, according to the parameters of the coach

如果他在防守者的位置之间看到一个黄色的正方形,则表示他们按照教练的指示做对了

If it is red, they did it wrong." Scores just got faster: Download the appThis is the level of detail now typical at top-level clubs thanks to the work of men like Saavedra, a Catalan with a PhD in neuroscience now bringing his expertise to football

如果它是红色的,则说明它们做错了。”得分更快:下载应用程序由于像Saavedra这样的人的工作,现在这是顶级俱乐部中常见的细节水平,他是加泰罗尼亚人,拥有神经科学博士学位,现在他将足球专业知识

Confirmed clients include Seattle Sounders, Santos and Nice, as well as Spain and Portugal

已确认的客户包括西雅图测深仪,桑托斯和尼斯,以及西班牙和葡萄牙

Barcelona are reportedly among another 80 clubs with whom he is working

据报道,巴塞罗那是他与之合作的另外80个俱乐部之一

Not everyone appreciates his input

并非所有人都赞赏他的意见

"I am the guy telling the coach when the player is doing something wrong

“我是在告诉球员什么时候做错事的人

One player once turned to me and said: "So you are the policeman."" Saavedra"s next move, through the company that he co-founded, Metrica, could be his most significant yet

一位玩家曾经对我说:"所以你就是警察。"“ Saavedra通过他与他人共同创立的公司Metrica的下一步行动可能是他迄今为止最重要的

The plan is to open up a version of their video analysis tool to the masses so that tracking data is no longer only accessible to data scientists at the world"s richest clubs

该计划是向大众开放其视频分析工具的版本,以便不再仅让世界上最富有的俱乐部的数据科学家可以访问跟踪数据。

A simpler platform is already being used by tech-savvy clubs like Peterborough United and Stockport County

精通技术的俱乐部(例如Peterborough United和Stockport County)已经使用了更简单的平台

Now they are introducing a free version of the tool that can be used by anyone with a camera phone and an appetite for analytics

现在,他们推出了该工具的免费版本,任何有照相手机和分析需求的人都可以使用该工具。

It could change the game

可能改变游戏规则

"By having these people in the shadows, you are stopping the development of football," he argues

他说:“通过让这些人处于阴影之中,您正在停止足球的发展。”

"All of these people can bring a lot of ideas, a lot of cool analysis." Saavedra"s own journey began in the Netherlands where he studied molecular neuroscience after having spent three years working for pharmaceutical companies in London

“所有这些人都可以带来很多想法,很多很棒的分析。” Saavedra自己的旅程始于荷兰,在伦敦的制药公司工作了三年后,他学习了分子神经科学。

"My topic was spinal-cord regeneration so it was completely unrelated but I did a lot of tracking experiments in the lab," he explains

他解释说:“我的主题是脊髓再生,因此完全无关,但是我在实验室做了很多跟踪实验。”

"I tracked mice and rats in my experiments." It was in Amsterdam that he met Bruno Dagnino, an Argentine studying for his own PhD in cognitive neuroscience

“我在实验中追踪了老鼠。”在阿姆斯特丹,他遇到了阿根廷布鲁诺·达格尼诺(Bruno Dagnino),他正在研究自己的认知神经科学博士学位。

"He was following the eye movements of humans and monkeys." Essentially, they were using tracking data

“他正在追踪人类和猴子的眼球运动。”本质上,他们使用的是跟踪数据

"It does not matter whether it is a mouse, an eye, a football player," says Saavedra

萨韦德拉说:“是老鼠,眼睛还是足球运动员都没有关系。”

"At the end of the day, it is just a data point that moves in time

“归根结底,这只是一个随时间变化的数据点

Just don"t tell the players." Bonding over a passion for football, they joined forces with award-winning video producer Enzo Angilletta, also from Argentina, with a view to changing football analysis forever

只是不要告诉球员们。”出于对足球的热爱,他们与同样来自阿根廷的获奖视频制作人Enzo Angilletta联手,以期永久改变足球分析

"One of our biggest advantages is that we do not come from that world

We came into it with an open mind

我们以开放的心态进入

We are big fans and we know about data

Information was flooding the market

信息充斥市场

Betting companies were collecting plenty of data for their own purposes

博彩公司出于自身目的收集大量数据

Broadcasters displayed it on screen

广播员将其显示在屏幕上

But the clubs themselves were playing catch up

但是俱乐部本身正在追赶

"We wondered what clubs were doing with all this data because we saw on television that there were heatmaps and statistics saying how far players had run," says Saavedra

萨维德拉说:“我们想知道俱乐部在处理所有这些数据是什么,因为我们在电视上看到有热图和统计数据表明球员跑了多远。”

"We found out that clubs had no expertise

“我们发现俱乐部没有专业知识

Most clubs did not have access to the data and even if they did, they did not have the people there to analyse that data." After toying with the idea of forming a consultancy company, the science students soon appreciated that football worked differently

大多数俱乐部都无法访问数据,即使他们能够访问,也没有那里的人来分析数据。”在组建咨询公司的想法之后,理科学生很快就意识到足球的运作方式与众不同

"Football people are used to watching football

“足球人们习惯看足球

You can show them a graph or a table but in the end, they want to see it to believe it." Video was the key

您可以向他们显示图形或表格,但最后,他们希望他们相信它。”视频是关键

"We told him we were all from Argentina

“我们告诉他我们都是阿根廷人

It was a small lie

这是一个小谎言

I am not but I can fake the accent." With their foot in the door, Metrica was soon supplying some of the biggest clubs in world football - and these sides were paying significant sums of money for their services

我不是,但我可以伪造口音。” Metrica很快就为世界足球提供了一些最大的俱乐部,而他们为此付出了巨额资金

Now armed with their own data science departments, these clubs utilise the data in weird and wonderful ways, each with their own metrics to determine the success of every potential pressing situation or the efficiency of every entry into the final third of the pitch

这些俱乐部现在拥有自己的数据科学部门,以怪异而奇妙的方式利用数据,每个俱乐部都有自己的指标来确定每种潜在紧迫情况的成功或进入最后三分之一市场的效率

It is slightly curious that having begun by working for Champions League winning clubs, the plan now is to pursue clients at grassroots level, but there is a certain logic to the thinking

有点奇怪的是,从为冠军联赛冠军俱乐部工作开始,现在的计划是寻找基层客户,但这种想法有一定逻辑性

"It is a similar approach to Tesla," explains Saavedra

“这与特斯拉类似,” Saavedra解释道。

"When they started producing electrical cars, they were super expensive but the vision was that at some point everyone would be able to afford electrical cars

“当他们开始生产电动汽车时,它们非常昂贵,但愿景是在某个时候每个人都能负担得起电动汽车

In a way, that is what we have done

在某种程度上,这就是我们所做的

"If we wanted to go down the tiers, we could not force clubs to use cameras that would cost thousands of euros, that would immediately be a killer

“如果我们想降级,我们不能强迫俱乐部使用花费数千欧元的相机,那将立即成为杀手er

So we went with another approach that would be hardware agnostic, whether you had a phone or a sophisticated camera

因此,无论您使用的是手机还是复杂的摄像头,我们都采用了与硬件无关的另一种方法

"We know that every single game these days is being recorded

“我们知道这些天的每一场比赛都被记录下来

Even at amateur level, even children"s football

即使是业余水平,甚至是儿童足球

We needed a technology that could actually get data out of any media

"The result was that we developed a new tracking technology that allows us to track from absolutely any media - training games with a technical camera, television, drones, hand-held camera, it doesn"t matter

“结果是,我们开发了一种新的跟踪技术,该技术可以使我们从几乎所有媒体中进行跟踪-使用技术性摄像机,电视,无人机,手持摄像机训练游戏,都没关系

It automatically tracks the players and the ball on the pitch." A lighter version of Metrica"s software is already in use at clubs far down football"s pyramid

它会自动跟踪球员和球场上的球。” Metrica软件的较轻版本已在足球金字塔下方的俱乐部中使用。

Sean O"Callaghan, a performance analyst at Stockport, first utilised it when working at Peterborough, but was determined to bring this way of working to the National League

斯托克波特的性能分析师Sean O"Callaghan在彼得伯勒工作时首先使用了它,但决心将这种工作方式带入国家联盟

"When I came to Stockport, it was one of my biggest priorities to bring this in to help with the videos," O"Callaghan tells

O"Callaghan告诉他:“当我来到Stockport时,将其带到视频中是我最大的优先任务之一。”

"It was totally different and gave me everything that I needed without breaking the bank

“这是完全不同的,在不破坏银行的情况下为我提供了我需要的一切

It has shaved a hell of a lot of time off

它节省了很多时间

"With the quick turnaround after a Saturday game, you have only got Sunday before you are delivering another meeting on Monday for the Tuesday game

“随着周六比赛之后的快速周转,您只有到周日才能在星期一为周二比赛进行另一次会议之前

When I put videos together, the coaches were saying how this made things so much easier when delivering meetings

当我将视频放在一起时,教练们在说这如何使会议变得如此容易

"We are offering them a solution that means they can do the same work that the analyst at Barcelona does," says Saavedra

Saavedra说:“我们为他们提供了一个解决方案,这意味着他们可以完成与巴塞罗那分析师相同的工作。”

It could spark a wave of innovation

可能引发创新浪潮

Even those working in analytics do not know where it might lead

即使是从事分析工作的人也不知道它可能导致什么

"We believe that these amateur analysts will eventually replace the dinosaurs in the market

“我们相信这些业余分析师最终将取代市场上的恐龙。

They will slowly take up these spaces and if they are using it now for free, maybe one day soon they will be working for clubs and be demanding that they pay for it." From the right-back who does not know his distances to the players who forget where to stand at a throw-in, the bad news is that football"s new policemen are just getting started

他们将慢慢占用这些空间,如果现在免费使用它们,也许很快就会有一天,他们将在俱乐部工作,并要求他们为此付费。”球员忘记了掷界外球的位置,坏消息是足球的新警察才刚刚起步
