First, the offensive and defensive relationship of the mainstream formation
1、433
In the traditional sense, the 433 is a purely offensive formation, which usually consists of four defenders (central defenders and left and right defenders), three midfielders (also one defender and two wingers, two defenders and a front waist, one defender and two front waists, but usually three midfielders) and three forwards (left and right wingers and a center, two shadow forwards and a center). However, with the development of football and the improvement of attack and defense requirements, 433 has gradually become a balanced formation, which is what we often call total attack and total defense football (the most famous is the Dutch team). As far as modern football is concerned, Chelsea of Mourinho's generation and Barcelona of Guardiola's era are the most commonly used 433 formations. The former often has two wingers and a center, while the latter has two shadow forwards and a center. Therefore, the two coaches use this formation differently. Mourinho pursues defensive counter-attacks and tight counter-attacks in the center and frontcourt. Guardiola likes to control the rhythm through short passes in the frontcourt, and when he loses the ball, he will gather around and grab it on the spot. It can be seen that the biggest feature of the two is that the attack is based on the success of defense, while the defense is to ensure the possession of the ball by one's own team, thus transforming it into one's own offensive rhythm.
Second, 423 1
This is the most popular style of play in football now, which is actually a variant of Barcelona's 433 and the traditional 442. Retreat the two strikers into two wings, increase the defense of the midfield, especially the flank, and leave a striker with strong personal ability in front (usually a bridgehead, who can score or build the ball). At present, Germany and Spain are more likely to use this formation (but Spain is now fascinated by the 460 formation, that is, the no-front tactic, because there is no good striker to do 1). This formation is very clear in dealing with the relationship between attack and defense, that is, try to stifle the opponent's attack in midfield, so as to be able to quickly put into attack.
It can be seen from the two appeal formations that with the development of football, there are no defensive players and offensive players in a limited sense. In other words, modern football pays attention to the integration of attack and defense, and there is also a clear task without a clear division of labor. Whether you are a striker, a midfielder or a defender, you should always read the table on the court and know when to attack and when to defend. Blind attack will eventually lead to the forward movement of one's own defense line, thus being beaten behind by the opponent; Blindly shrinking defense will only fall into the opponent's rhythm (don't think that Mourinho's defensive counterattack is defensive retreat, and Mu Shuai's counterattack is really an active attack).
To sum up, in modern football, there can be no clear division between defense and attack. When assigning tasks before the game, you can make clear the defensive concept and main defensive core (take Barcelona as an example, the offensive core is Harvey, supplemented by Iniesta, and the terminator is Messi. Accordingly, the core of defense is busquets and Puyol. The midfield led by busquets built the first line of defense, and then Puyol and Pique organized the second line of defense in time, but at the same time, Pedro and Sanchez both returned to the midfield defense, except Messi, who was an arrow figure preparing to counterattack in the front line. )。 In short, defense is the source of attack, and attack is the team's first line of defense.
