FM09 played against strong teams such as Chelsea

This has something to do with the strength and staffing of your team. Roughly speaking, your strength is better than your opponent or about the same: then your home mentality can be slightly more offensive, and away games can use a balanced mentality. If you are weaker than your opponent, you should be more conservative in your mentality. The degree of freedom is generally in the middle. If there are many players with high technical creativity in the team, it can be slightly higher. When the scene is well taught, the degree of freedom is higher. If the opponent is pressing down, the degree of freedom should be lower. The width depends on the strength of you and the opponent's wing. In the FM game, the success rate of crosses from the bottom is actually very high (it's a British game, as long as you have a good high center forward), if the opponent's wing If the opponent is strong, such as Manchester United with Cristiano Ronaldo, then your width should be lower. If the opponent is mainly playing in the middle, then you can be wider. High width is suitable for offense, but lower width is better for defense. The passing method depends on the ability of your players. If it is a technical team, then short passes are good. On the contrary, if the players are not skilled, then long passes are better. Players with high creativity can pass more directly and pass behind the ball more. Note that in heavy rain or stormy weather, short passes are not so easy to use. Long passes or long shots are good choices. Pressing should be used more often when the opponent's teacher is strong, but it will easily lead to card losses. The formation is based on the specific arrangement of your team. For example, with AC Milan, I usually use 4321 or 4312, while Barcelona uses 433 and 4231. The Gunners are more suitable for 442. For Udinese, I use the double of 442. Defensive formation of defensive midfielder or 4141. The offensive line is generally mixed and adjusted according to the actual situation. For example, AC Milan focuses on breakthroughs in the middle, while Udinese uses double midfielders, so they mostly use a two-wing style of play. If the opponent retreats to defend, then more Go sideways. Defensive counterattack is a good tactic. It is not to defend first and then counterattack, but to counterattack quickly when the opponent is pressing, such as directly passing the long ball to the forward. Choose other tactics according to your team's situation. The Gunners can consider using the core play style while Inter Milan considers the offensive core tactics. The key still depends on the strength of your players.
