Fancy learning about soccer and its countless nuances, then look at this manual.
The best soccer books will go into quality detail on the formations and styles of play that work if your main aim is prevent the opponent from scoring. When a considered weaker club comes up against a good team, they will commonly play in a strict way that makes it very hard for the opponent to score. If you can prevent the opposition scoring, you're guaranteed to get at least a draw; even so, if you push for a goal in the later stages of the game, a club can snatch a victory. The West Brom owner would acknowledge how efficient this tactic might be, as in the past they actually have had some coaches that were experts at this style of play.
If you were to ask any trainer how to attack in soccer, nearly all of them would tell you that speed is one of the key elements. The greatest attackers actually have both quick feet and even quicker brains. A defence that has time to reorganise is one that is much harder to break down; so, it is essential that when a group gains possession they move forward quickly and do not faulter on the ball. It helps if the footballers are fast across the ground, as this gives defenders a real problem in that they have to give the attacker space. Soccer rules make it impossible for an attacker to linger behind defences, so they must be quick enough to run in behind without being offside. The AC Milan owner would anticipate the team’s attacks to actually have speed and likewise accuracy. There is no point in an attack being quick if it's going to be short lived, so, footballers must make the best decisions at speed. A mistaken pass can lead to possession being stolen, but if they can carry out the correct pass it will almost undoubtedly lead to a tremendous opportunity to score.
There are numerous technical soccer drills out there, and managers will utilise them to fine tune a squad and the players so that they all know what the game plan is. If a group does not have a thorough game plan, then they will perhaps struggle to collaborate. The St Mirren owner would of course anticipate the team to be organised in a way that each player knows the role they must play. If a team is organised well enough, they will become greater than the sum of their parts, and this is the main goal for a trainer or coach. There are countless examples of a squad that is perceived as weaker than the opposition, but they still overcome that gap in quality by being perfectly organised and executing the game approach.
