Football is a holistic sport, and if one player has more and more offensive tasks, then that means that the other player will also have more and more defensive tasks. Pen ~ fun ~ pavilion www.biquge.info

If you move one step forward in one place, then you need to balance that step back in other places. "A little here, a little there" all in order to have one more decisive advantage over the opponent.

This idea has led to the development of the goalkeeper as a tactical concept, and although it is not strictly a new tactical innovation, it has become popular on a large scale and has been used successfully by famous coaches such as Josep Guardiola, Juachim Loew, Robert Pochettino and Luis Enrique.

And Guardiola's move when he first joined Manchester City was even surprising, when Guardiola came to the blue moon and immediately asked to bring in goalkeeper Mark Ter Stegen from his old club Barcelona, Barcelona rejected Manchester City's request, Guardiola had no choice but to bring in Claudio Bravo, and now many people believe that Bravo's performance is not satisfactory compared to Joe Hart, who was squeezed out (judging from the work in hand).

A soccer team is made up of 11 players on the field, ten players and the last one - and the only one who can use their hands - is the goalkeeper, and their job is to be the team's last line of defense, which needs to be used to stop the opponent's shots.

For most teams, the value of a goalkeeper is judged primarily by how well he uses his hands to prevent the opposition from scoring, but there are a small number of teams who believe that a goalkeeper needs to be as good at his feet as he is at the level of his hands, even when his team has possession of the ball – this is the philosophy of the eleventh man. No matter who has the ball, a goalkeeper will not be less associated with his or her own team at all.

Who is the janitor? To put it simply, a goalkeeper is a goalkeeper who controls the space behind the back line by pushing forward and as close to the back line as possible, and when his team has possession of the ball, he can actively participate in the team's attack and defense, thus becoming the eleventh man of the team.

Modern football is all about space management and control, and being able to push your goalkeeper forward behind the back line can help teams control space effectively.

The goalkeeper as a football tactic dates back to the late 19th century, and unlike many other football tactical innovations, the goalkeeper tactic really originated in England. The first goalkeeper in history was former Stoke City and Sunderland goalkeeper Lee Richmond Ruth.

Ruth mainly used FA rules, which allowed goalkeepers to handle the ball with their hands in their own field, but not with their hands, and would send the ball forward across the half-line before attacking.

Ruth played this role in six teams from 1895 to 1912, and his retirement coincided with a change in FA rules that limited the range of goalkeepers to handle the ball, changing from their own half to their own box, making him a pioneer in the goalkeeper role.

The goalkeeper is very similar to other roles on the football field, always evolving according to the change of the rules. The introduction of the offside rule in 1925 meant that the space between the last defender, the last attacking player and the goalkeeper became a fiercely contested area between the two teams, and pushing forward allowed the defenders to play offside tactics, which required the team to form a high defensive line, which would expose the team to the threat of through balls and overhead balls - those teams with high defensive lines also faced this threat, so it required the team's goalkeeper to have a sense of the goalkeeper and control the space. Especially when the defenders on this side are slow.

Following Ruth's retirement from the top flight, Lev Yashin and Gyula Grošić were the goalkeepers who took over the baton from the goaldefenders, and both were known for their striking and ball handling at their feet, and in fact Yashin could often use his long hand tosses to launch counter-attacks.

The great Dutch star Johan Cruyff once said, "In my team, the goalkeeper is the first attacking player and the center forward is the first defensive player. He values the technical ability of every player in his team, including the goalkeeper. His football philosophy has greatly influenced his successor, Pep Guardiola, whose tactical system is all about controlling space and breaking through the opponent's continuous pressure to score goals. From this point of view, the goalkeeper has become quite important as the eleventh man of the team.

In football, 80% of the time either one side pushes the ball forward and breaks through the layers of defense of the other side; Either one side tries to stop the other side from moving the ball forward with ease and cleanness, which is the basis of offense and defence, so this is why teams generally coach the most prominent forwards to harass the opposing attacking organization at all costs. This is the first stage of the attack for the team in possession, and this move by the opposition often poses a huge risk for them, because once they lose possession, the opponent is less away from the goal and can attack directly.

However, when opponents use attacking players (in equal numbers) to exert pressure, teams that have the ball can often be an important means of moving forward by using defenders and goalkeepers to organise attacks.

When the first kick of the team is clean and clean, then everything is much easier. - Juan Manuel Lillo.

Pep Guardiola used this theory in his relatively short career and it was a huge success, winning 22 trophies in just eight years, when the first player to play that role was now Middlesbrough goalkeeper Victor Valdés.

One of the principles of Cruyff's tactical philosophy is to compress the space on the pitch and keep the opponent in as little space as possible by pressing high when they have the ball. If this is successful, then it will be followed by subsequent pressing, with the midfielders pressing forward to support the forward line and the defenders pressing forward to support the midfielders. This tactic allows the team to create offsides and regain possession, but it also exposes itself to the opponent's well-placed overhead and through balls. Therefore, the team needs their goalkeeper to press forward and support the team's pressing by controlling the space behind the back line, thereby reducing the threat of the opponent's overhead ball and through ball.
