The referee officiating the match was England's Clattenburg, who is doing a thankless job in today's game.

The 42-year-old has gone from being an obscure assistant referee to a glittering referee in the European Championship final, and has encountered too much criticism and accusations along the way, Clattenburg, who was born in a small town in County Durham, England, and is a Newcastle football fan.

In 1990, at the age of 15, Clattenburg began to work as a referee, became a national referee in 2000, began to enforce Premier League games in 2004, and became an international referee certified by FIFA after 2006, becoming the fastest promoted English referee after the war.

A Merseyside derby in 2007 was Clattenburg's first taste of the "enemy of the people", when Everton's Hibbert deliberately fouled Gerrard, and Clattenburg decisively awarded Liverpool's penalty.

And he had already pulled out a yellow card to warn Hibbert, but after a brief exchange with Gerrard, he changed his mind and instead pulled out a red card to send Hibbert, but in stoppage time, Carragher's suspected foul on Lescott in the box was not awarded a penalty, and Liverpool won 2-1, and after this huge controversy, Clattenburg did not officiate at Everton for five years.

Five years later, Clattenburg was thrust into the limelight again in the 2012/13 Premier League Round 9, a 3-2 win at Chelsea, with Branislav Ivanovic and Fernando Torres sent off in quick motion, and a slow-motion show that Hernandez's strike was offside, but worse than all that was the Chelsea Chelsea formally accusing the FA of Clattenburg's inappropriate remarks about Mikel.

After the police intervened in the investigation, Clattenburg was suspended for a month, and even his family was abused by extreme fans, but in the end, all parties agreed, Clattenburg did not abuse the player, Chelsea made a public apology, according to the investigation Clattenburg has a north-east English accent, Mikel's pronunciation is similar to a monkey, and the racial discrimination storm has ended.

Later in his refereeing career, Clattenburg continued to be the protagonist on the pitch from time to time, making jokes about forgetting to carry a yellow card, being banned by the FA for not going to the venue with the referee for a concert, and blowing three penalties for Liverpool at Old Trafford.

On the one hand, there is the infamy of "faint whistle", on the other hand, there is a glittering record on the resume, the 2012 League Cup final, the 2012 Olympic men's football final, the 2014 UEFA Super Cup, and then the cup final hat-trick, Clattenburg can be described as a success.

He became the second referee to officiate in the finals of UEFA's two top competitions in a row after Portuguese Proenka in 2012, and is even expected to surpass Taylor, Webber and other famous golden whistles to become the most successful referee in England's history.

It's hard to imagine how many setbacks a referee goes through before he succeeds, because fans are accustomed to attributing their losses to the referee's misjudgment, and the maturity of television technology will magnify their mistakes infinitely, and to be able to stick to such a thankless job, Clattenburg's love for the game is no less than that of any other star.

'The game is about to start, this is Leicester City's home game against Chelsea, we saw this game against Clattenburg, it seems that the FA is very serious about this game.

'We saw Leicester City playing at home, Shakespeare and he put out a 442 formation, which was not what we expected, and Shakespeare must want to win Chelsea on his home turf.'

Indeed, when Kodic got the starting line-up for Leicester City, he found that the lineup was similar to what he wanted, so Kodic did not make adjustments to his own tactics, in his opinion, being a top team is to let the opponent meet him and adjust their tactics, not to adjust the tactics according to the opponent.

The 442 formation is characterized by a balance between offense and defense, regardless of the arrangement of personnel to the division of responsibilities, each line and position can complement each other, and can be protected, and when attacking, they can support and cooperate with each other. The 442 formation is one of the most common formations in modern football.

"Shakespeare's goalkeeper was No. 1 Casper. Schmeichel, back four: 2 Danny Simpson, 5 Morgan, 15 Maguire, 28 Fuchs, right midfielder No. 26 Mahrez, left midfielder No. 11 Albrighton, in the midfield sent young player Matthew. The combination of James and Ndidi, double striker Slimani of No. 19, No. 9 Vardy, Leicester City after an unsatisfactory season, in the first four rounds of this season encountered Manchester United, Arsenal, Chelsea three Premier League giants, the first three games 1 win and 2 losses accumulated 3 points.

The commentator is still introducing the situation of the players, the starters of both sides entered, Liu Neng sat on the bench, the players entered Clattenburg has blown the whistle for the start of the game, and Chelsea, who have got the right to kick off, soon sounded the horn of attack.

Pedro, who started this game, has not started several games, and he and Segura have formed a double striker, and it is because of so many internationals that these substitutes have a chance, and this is the way this world is, there are gains and losses.

"Chelsea on the field has been attacking, it seems that Shakespeare is determined to win all three points at home in this game, Leicester City's 442 formation is balanced in defense and defense, Chelsea's formation was originally a 433 formation, in this game it became Segura in the front position, it became a 3511 formation, goalkeeper Courtu started, Valludiger returned to the left-back position and David Luiz and Azpilicueta formed a back three, Fabregas was behind Pedro, and Marx on the left side. Alonso and Kanteda played on the left, while Tiemoue Bakayoko and Moses on the right were handed to Segura up front, with Pedro behind Segura. ”

"In the first 10 minutes of the game, Chelsea attacked fiercely, and there were already a few shots in front of the Leicester goal, if it wasn't for bad luck, there would have been a goal, this is half of Chelsea's substitute lineup, but the substitutes are probably going crazy, and they are full of energy, and they also want to show themselves to enter the main team, Leicester City's players seem to be stunned, and for a while, they can only see their passive defense throughout the game, and they can't organize an effective attack at all, and the counterattack is nowhere to be seen."

'It's been almost 12 minutes since the start of the game and we've seen Chelsea attacking all the time, they've been aggressive in tackling and they've been counter-attacking when they have lost the ball, so it's very physically demanding.

Shakespeare stood on the sidelines, he found that he was overestimating his team this time, it seems that he hopes to win the game is not very hopeful, his goal is now possible to be broken at any time, and he has no good way, he can only let the players actively defend, now it is impossible to attack, the defense is also precarious, or wait for Chelsea to attack tired and then counterattack, they play like this has a lot of physical consumption, it seems that they can only do this.
