The most controversial offside in football matches. Who is right? In fact, it will be clear if you master this principle!
The World Cup is in full swing, and whether you are also fouled about offside while watching the game is the most debated question in the football game. In fact, literally speaking, offside means that the offensive side crosses a certain line of the defensive side in the opponent's half, and is called offside. In short, it is the offensive team member who runs behind the defensive team member and is closer to the opponent's goal than the defensive team member.

Then the standard for judging whether it is offside is this line. It is based on the second-last player on the defense side. It draws a dynamic boundary line parallel to the goal line. The area from this line to the goal line is the offside area, and the offensive player is located in this area. However, offside does not mean a foul. Only when the offensive player in the offside area encounters the ball and interferes, or benefits the team, will be called a foul.
So the key point of whether to offside is the second-last player on the defense. However, since generally goalkeepers are active within the penalty area, that is, the large rectangular area in front of the goal, also known as free throw area . The last defensive player generally stands at the second-last position in the team before the goalkeeper, so many people mistakenly believe that offside is based on the opponent's last defensive player. In fact, this is not the case. Even if the goalkeeper runs to the opponent's half, it is based on the principle of second-last number.

So I mainly grasped this line and it is not difficult to judge whether the offside foul is made. Generally, even if there is only the feet or part of the body torso, the behavior of receiving the pass in the offside area is also an offside foul. However, if there is no actual behavior in this area, it is just offside and no foul.
Then if the offensive player does not pass the ball, but attacks by himself and quickly passes the opponent's defense player, and when it is judged that the offside is no longer the opponent's second-last place as the baseline, the offside area is used between the baseline and the goal line.
If the offensive side has another player receiving the ball in this area, it is an offside foul. So if it is a striker who dribbles into the ball, he or she either chooses to shoot by himself or passes the ball back to his own players behind him, rather than to players in the offside area. So in general, whether an offside foul is to pay attention to the two key points of position and whether the pass is received.

What exactly is an offside foul? In addition to common offside fouls, what other offside fouls are not common?
In fact, simply put, an offside foul is in the opponent's second-to-last defensive player, closer to the opponent's goal line, and receiving a pass is an offside foul. Then if you don't catch the ball, even if you offside, it will not be considered a foul. It wouldn't be considered a foul if the offensive party really had a player wandering around in this area or standing stupidly.
And even if you don’t catch the ball, you may cause an offside foul, because when you are in an offside position, it will be an offside foul by interfering with the defense and making the party profit is also an offside foul, even if you don’t catch the ball, it won’t work. First of all, you use your body to block the opponent's sight in an offside position, because although this behavior does not touch the ball, it seriously interferes with the opponent's defense and can make your own profit and get a more likely chance to score goals. Such behavior will be judged to be offside.

In addition to interfering with the goalkeeper's behavior, interfering with the opponent's behavior by competing for the ball in the offside position is also a category of offside foul. Because the purpose of fighting for the ball is to interfere with the opponent, let your side grab the ball and make a profit. Although such behavior is not wrong on the court itself, the position is a more favorable offside position, so such behavior is naturally prohibited by the rules.
So from the above description, we can see that offside fouls are not only interfering with the opponent's behavior, but more importantly, making one's own profit.For example, when his side was attacking the ball, an offensive player entered the offside area, but he did not interfere, but was just in this area. Logically speaking, he should not be considered an offside foul. However, the environment of the stadium changes rapidly. During the competition, the football was kicked in front of him, or the shot was unsuccessfully ejected into him, and he did not take the initiative to catch the ball. It was equivalent to the free shot that the ball was successfully shot, and it would be easy for the referee to be punished for an offside foul.

Because although this player did not commit fouls when entering the offside area and in the entire offside area, he had already obtained a more favorable position when he entered the offside area. This favorable position caused him to pick up the ball and successfully shoot, so he would be considered a profit-making offside and also a foul.
offside foul was not only a matter of position, but also interference and profit may also be judged as foul. So what are the special circumstances besides these?
Although in addition to the flag-raising edge, there are also high-speed camera assistance in the football game. However, whether it is judged as an offside foul is decided by the referee, so there are many debates about offside, and sometimes the penalty is even considered as black whistle . But overall, the referee's penalty is basically strictly based on the competition rules, but sometimes the audience may misunderstand because of their lack of understanding of the rules.

And we can see the offside setting. Although it avoids the dilemma of the defensive side, it also curbs the momentum of the offensive side, which easily makes the offensive side restrain. In order not to foul, football games are prone to become mediocre and lacks the offensive passion, so the rules about offside are also constantly improving. For example, in 1925, the offside baseline was changed from the third to the bottom of the defense to the second to the second to the current one, which is actually to encourage more offenses.
The newly modified intentional touch principle is also to reduce the risk of offside fouls. For example, as we mentioned above, the offside player on the offside position is in an offside position and does not interfere with the behavior or take the ball, but if the football shot is unexpectedly obtained, he will still be judged as offside fouls.

However, this situation has changed now, that is, if the defensive player intentionally touches the ball, then the offensive player will not be considered an offside foul even if he successfully grabs the ball in the offside area. The key point is whether the defensive players have intentional touching the ball. For example, behaviors like tackles are considered intentional touching the ball even if they do not touch the ball in real time. However, in the rules, it is also stipulated that the defense party's saving the ball is not intentional touching the ball. So how to define the save and intentional touching the ball are often found in the subjective judgment of the referee, so this is also the reason for the debate in many cases.
After all, each side will look at it from a perspective that is beneficial to them. However, after we understand these basic rules about offside, ordinary audiences can basically figure out this issue under normal circumstances. If they really don’t understand it, just hand over this task to the lineman holding the flag and the referee who will ultimately judge.
