Among other qualities, a goalkeeper must have awareness, positional awareness, speed and good technical ability, and must have an excellent ability to read the game, just like any other player on the field, pinching you when the opposing striker gets the ball and intercepts the football.

Much like any other football tactic, using the goalkeeper tactic is not a good or bad option in itself, and whether or not it will always be beneficial to the team depends on how the goalkeeper executes it and how other players react to it.

First of all, asking a goalkeeper to stay away from the penalty area he is guarding arguably deprives the goalkeeper of his innate advantage – the right to use his hands. This means that if a goalkeeper is fighting the opposing striker for a through ball, the goalkeeper will be at a potential disadvantage. Therefore, if a goalkeeper fails to time the interception, he will expose the unguarded fans to the opposing side.

In addition, in order to intercept behind the back line, the goalkeeper's starting position must be relatively high on the pitch, so it is easy to be exposed to the threat of the opponent's half-court long-range shots.

The doorman tactic is a high-stakes tactic that is dangerous because of the potential consequences of poor execution. If the last defender makes a mistake and gives the ball to the opposing striker, then he can only hope that his goalkeeper will save him, on the other hand, if the goalkeeper is the player who makes such a mistake (the last player of the team), then he can only pray.

So, like any other football tactic, there is no good or bad tactic in itself, and how to use it well depends on the team, the players and the coach who want their team to execute the tactical philosophy.

It's a high-stakes tactic for teams that crave total control and are willing to take risks to implement goalkeeping tactics, and when used in the right way, goalkeepers can have a very wide range of positive effects on a team's overall attack, such as increased consistency and penetration.

However, not all teams can use it, and when there is a problem with execution, the consequences are often very immediate and fatal, so in order to achieve maximum success, it is the onus for the team to find the right balance.

In European football, the use of goalkeeper tactics began with Victor Valdés after Josep Guardiola took office at Barcelona, and after Guardiola left Spain, he coached Bayern in the Bundesliga, with Manuel Neuer.

Despite Pep Guardiola's departure, new coaches continue to use goalkeeper tactics, from Victor Valdés to Claudio Bravo and now Marc Ter Stegen.

Goalkeepers are now more common in the Bundesliga and La Liga, but in Serie A, Ligue 1 and the Premier League, traditional goalkeepers are still the mainstream.

After Pep Guardiola arrived at Manchester City, he became the first person in the Premier League to use goalkeeping tactics, but unfortunately Bravo's performance in the Premier League made Guardiola take the blame, which also shows the high-risk nature of goalkeeper tactics.

After Arsenal's substitutions in the second half, the tactics became very aggressive and risky, Zhang Zhetian expanded the scope of movement, frequently attacked, participated in the team's attack and defense, and in the second half, the 53rd minute attack to destroy Hazard's breakthrough pushed the game to a climax.

With Oliver Giroud on the pitch, Arsenal, who were more involved in the pitch, put Chelsea under immense pressure, with a couple of neat high balls that Giroud's header would have worked had it not been for Thibaut Courtois's hard save.

Sudden substitutions to change tactical play, played Chelsea by surprise, occasionally several counterattacks were destroyed by the bold Zhang Zhetian, Antonio Conte sweated profusely and waved his arms on the sidelines and shouted, Arsenal suddenly changed the style of play at the beginning of the second half, Conte was puzzled at first, taking such a risky style of play at his home stadium, he was not afraid of being beaten into a sieve at the back?

When he saw Zhang Zhetian's performance, Conte suddenly realized, no wonder he is so confident, this Huaguo goalkeeper is a goalkeeper, and it is no wonder that he is Ter Stegen's junior brother.

However, the disadvantages of this style of play are not small, Chelsea occasionally counterattacked several times, Arsenal's players did not return to defend in time, unable to stand in position, if it were not for the fast and accurate attack of Zhang Zhetian, Chelsea would have scored a goal.

"Defend low, play counter-attacks, and go to the wings!" In response to Arsenal's changing style of play, Conte called Kurt Zouma and Willian to the front to lay out the tactical details of their arrivals.

Arsène Wenger in the stands saw this scene and immediately used a communication tool to say to the assistant coach Steve Boulder on the sidelines: "Tell Welbeck to warm up and get ready to play." ”

In the 56th minute, Gabriel Paulista, who played as a guest at right-back, had limited assists, and Mesut Ozil, who ran to the right, was covered by Theo Walcott and crossed from the right side of the penalty area, and Giroud, who pressed forward, pushed the ball high under the pull of David Luiz.

Conte, who was on the sidelines, yelled unhappily and told the wingers and midfielders to protect their ribs and not let Arsenal easily cross from the wings.

In the 58th minute, Chelsea made a substitution, with No.5 Kurt Zouma replacing the defence-poor Cesar Azpilicueta and No.22 Willian replacing the slow Pedro Rodriguez.

In the 61st minute, Walcott's dribbling was cut off, Marcos Alonso took the ball and ran to the Arsenal half on the side, and Paulista chased back, but obviously couldn't keep up.

In the 62nd minute, Alonso crossed from the left side of the penalty area, and Diego Costa, who quickly stepped forward, jumped forward with a header that was lifted off the crossbar by Zhang Zhetian.

Referee Martin Atkinson didn't blow the whistle for a Chelsea corner, as an electronic screen was raised on the sidelines and Arsenal used up their last substitution to replace Walcott with No.23 Danny Welbeck.

In the process of substitution, Zhang Zhetian walked up to Schkodran Mustafi, Laurent Koscielny and others and whispered: "You keep an eye on the others, but the No. 3 leaves him alone." ”

Several teammates glanced at each other, and then looked at Zhang Zhetian with strange eyes.

Players who can play at Arsenal are not stupid, Héctor Bellerin was injured and was excited to come forward for him to face the referee, this time when they defended, they did not stare at Alonso, the culprit who caused Bellerin's injury, and fools know what he is going to do.

As the captain, Koscielny frowned and looked at Zhang Zhetian and said: "The game is not over yet, don't do anything that harms the interests of the team." ”

The fingers of Zhang Zhetian's hands couldn't stop moving, the corners of his mouth curled, and he said: "Don't worry, captain, I promise not to do anything that harms the interests of the team." ”
