The technical staff is the group responsible for creating formations and making in-game tactical changes. A lot more about this below.
While football formations and tactics can vary greatly, teams that wish to win trophies frequently opt for offensive football formations. Producing an attack-heavy formation will primarily depend upon the quality of players readily available and the variety of abilities they have. For example, if you have some gifted wingers and centre forwards in the team, the 4-2-4 formation can be very effective. In this formation, the defense line would be composed of two centre backs and two full backs who have both defensive and offensive duties. The full backs are expected to support the attack by overlapping with the wingers. The two midfielders also have offensive and defensive responsibilities. They are required to break up attacks at the midfield level and also launch counterattacks when they intercept the ball. The Aston Villa former owner would agree that the offensive line is generally composed of two wingers on the flanks and two centre-forwards.
Widely considered one of the best football formations for versatility, the 4-1-2-1-2 is a layered tactic that culminates in a strong midfield presence while also providing solutions in the last 3rd that other tactics are not likely to be successful at. This formation is known for the width it offers as many players play closer to the flanks, thus why it's also known as the diamond or christmas tree formation. The shape and player placement can help the team dominate possession and dictate the tempo of the game. It is also among the most versatile strategies as coaches can quickly make tactical adjustments to reflect particular objectives. For example, the full backs can be advised to push forward to help the attack when the team needs to score. On the other hand, the Crystal Palace former owner would confirm that the attacking midfielder can drop back to support the defense if the team wants to maintain the score.
Whether they wish to keep their ranking on the table or are cognisant of the attack expertise of the rival, there are lots of reasons football clubs in some cases choose defensive football formations. There are obviously different formations and levels of defensive strength however the 4-5-1 is without a doubt the most widely known for its defensive strength and tactical discipline. Utilising five midfielders, this formation aims to control the midfield area by erecting a barrier covering the back line. The numbers advantage isn't the only perk to this formation as player positioning also plays a huge part in keeping order and control in the midfield location. The two midfielders on the flanks cover the full backs, the defensive midfielder in the center intends to interrupt attacks when they happen, and the two central midfielders play box-to-box, providing both attacking and defense assistance. This is something that the AC Milan former US owner will very likely understand.
