A corner kick in football is played when the defender team's player touches the ball last and crosses the goal line.

It is common for defensive teams to kick out the ball and run away into a corner kick to prevent opponents' opportunities. However, the defense team may decide the score from the counter by connecting the ball without running away to the corner kick. Even Japanese delegates who finished in a dramatic draw with the Senegalese side at the 2018 FIFA World Cup, the clearance before the goal of the Gengari Genki player became the path to the opponent and led to the first goal. Haraguchi players after the game as "might be was better that fled to the corner Maybe. It is," Cod Liver "because it is there. Because honest corner also scary, there was also the feeling that you do not want to a corner," said As you can see, it is very difficult to judge whether you should escape to a corner kick or not.

Michael Kalei, a statistician, analyzed the data on how probably the goal will be born from the corner kick in order to judge whether it should be a corner kick or not by a real number. Karei gathered the data of the game for three years in England's Premier League, Germany's Bundesliga, Spain's Riga Española for two years, and the corner kicks for about 20,000 rounds performed in that match I am investigating what kind of result it led to. Incidentally, the survey included various factors such as a score determined directly from the corner kick, a penalty finally decided in the flow from the corner kick, and a penalty to be given in the play from the corner kick I will.

According to this survey, the probability that a team kicking a corner kick will connect to the shoot is about 35%, and the probability of goal determination is 3.5%. However, if the team that kicked a corner kick got PK in a series of play and decided the score as it is, it seems that if the team kicking a corner kick shoots a shot, it scores with a probability of 10% .

At the corner kick, high-ranked players gather in front of the goal from the attacking team. In football, there are many cases where the center back player is high stature, so at the time of a corner kick, the center back of the offensive team often gathers before the opponent goal. Representatives of the Japanese national team are also frequently seen as Miki Yoshida, who is tall in height, going up to the goal at the time of a corner kick, so there are times when Miki Yoshida actually decides the goal from a corner kick. However, many players who are key to defense are in front of the opponent's goal, and if they are robbed of the ball, there are many cases where you can set up a quick counter and the team on the offensive side will be pinched at once.

As a result of examining 20,000 corner kicks, the number of times the team kicked a corner kick could not be connected to the shoot was "about 13,000 times". The case where the team that kicked the corner kick got the counter is "about 1800 times", that is, the team that kicked the corner kick with the probability of 9% will receive the counter. Mr. Kalei said that he decided whether or not the team got a counter by "whether the team was invaded by the attacking party ". And the number of times that it was brought from the counter to the shoot was "526 times", of which the score was "72 times". The probability that the counter attack brought to the shoot leads to the score is 13.7%, which is 40% higher than the average. This means that if you take it to the shoot at the counter from the corner kick, you get a score with a high probability.

However, if you think of "the probability that teams who kicked corner kicks are scored by receiving counters", the probability is only 0.4%.

Kalei ultimately said "Defenders should do so if there is a chance to escape to a corner kick at Attack Third, the given opportunity is not more dangerous than the middle shoot of 30 yards (about 27 meters), better at the team There is also the possibility of offering attack opportunities (opportunities of counters) ".

About the scores of Japan's go-ahead scenes Hiroki Sakai pointed out in an interview after the game that "Although it was okay to escape to CK if you really wanted to be a no-risk, I was trying to throw in, but I did not try wrong in as we, but is difficult to momentarily, the "free" or, or I should "corner" or Iere " says , has defended the play of Haraguchi players. Kawashima Eiji, a goalkeeper in the position to send instructions to the defense team in this scene, said he gave a voice of "clear" and coaching.
