Hello and welcome to the first lesson of Module 2. In the previous module, we built your analyst's toolkit, finishing with how to use telestration to communicate tactical ideas clearly. Now, we begin to apply those skills to the art and science of corner kick strategy.
Today's learning outcome is to compare the principles of inswing, outswing, short, and driven corner deliveries. The choice of delivery is the foundational decision upon which every corner kick routine is built. Understanding the unique characteristics, advantages, and disadvantages of each type is essential for any set-piece coach.
We will break down each delivery style, examining its trajectory, the tactical situations it suits best, and what the data says about its effectiveness.
The Fundamental Choice: Inswing vs. Outswing
The most common decision a coach makes is whether to use an inswinging or outswinging delivery.
- An inswinger is a ball that curls towards the goal. This is achieved by a right-footed player taking a corner from the left side, or a left-footed player from the right side.
- An outswinger is a ball that curls away from the goal. This is achieved by a right-footed player from the right side, or a left-footed player from the left.
Let's explore the tactical implications of each.
How to Attack Corner Kicks in Football?
The article 'How to Attack Corner Kicks in Football?' provides an excellent tactical breakdown of inswinging and outswinging deliveries. It explains how the curl of the ball influences the attacking and defensive setup.
Please read the two short subsections titled 'In-Swing' and 'Out-Swing'. As you read, focus on: In-Swing: Why is it considered effective for attacking the near-post area? Out-Swing: How does the ball's trajectory benefit attackers, even though it moves away from the goal?
As the article explains, an inswinger is inherently more dangerous to the goalkeeper. It forces the defence to position a player on the near post to prevent a direct goal and can create chaos with just a slight touch. However, this high reward comes with high risk.
Conversely, an outswinger is often seen as a safer, more controlled delivery. It allows attackers to run onto the ball, which can help them generate more power in their headers.
This tactical trade-off is also reflected in performance data, though the conclusions can sometimes differ depending on the competition.
Are Corner Kicks Becoming Irrelevant in Football?
The Tifo Football video 'Are Corner Kicks Becoming Irrelevant in Football?' discusses the statistical debate between inswingers and outswingers. It highlights a common trend in European leagues.
Watch the segment from 01:37 to 03:57. Pay close attention to: The statistics on the prevalence of outswinging corners versus their goal output. The risks associated with inswinging corners (e.g., failing to beat the first man). The characteristics of an ideal inswinging delivery.
The video highlights that while outswingers are more common, they may be statistically less effective. This brings up a key theme for a set-piece coach: common practice is not always best practice.
Now, let's look at some specific data to make this comparison concrete.
Take a moment to analyse this data. Notice that while outswingers generated a slightly higher xG per corner, inswingers had a better goal conversion rate and a higher Expected Goals (xG) value per shot. This suggests that while it may be harder to generate a shot from an inswinger, if you do, it's more likely to be a high-quality chance.
To add another layer, a detailed analysis of the 2022 FIFA World Cup found that outswinging corners were actually the most productive type for generating both goal attempts and goals in that tournament.

This research paper on the 2022 World Cup offers a different perspective, backed by data from the tournament.
Read the paragraph starting with 'The analysis of corner deliveries...'. Notice how its findings on outswingers compare to the Premier League data and the Tifo video.
What does this conflicting data tell us? It proves there is no single "best" delivery. The effectiveness of a corner depends on a team's specific players, their routines, and the defensive systems they face. An outswinger that allows your best aerial attacker to get a running start might be more valuable to your team than a statistically "superior" inswinger.
Alternative Deliveries: Short and Driven
While inswingers and outswingers are the most common, they aren't the only options. Short and driven corners offer unique ways to disrupt a defence.
Short Corners
A short corner involves passing the ball to a nearby teammate instead of delivering it directly into the penalty area. The primary goal is to change the angle of attack and pull defenders out of their organized shape.

Let's return to the Tifo video, which also makes a strong case for the effectiveness of short corners.
Watch the short segment from 03:57 to 04:20. Focus on the tactical advantages a short corner creates.
As the video states, short corners are statistically very effective. They allow for:
- Better angles for a subsequent cross.
- Unpredictable movements that force defenders to react.
- A higher probability of beating the first defender.
The main drawback is that a poorly executed short corner can waste a good opportunity and, if possession is lost, can leave the attacking team vulnerable to a counter-attack.
Driven / Flat / Straight Corners
This delivery is less common but highly specialized. It involves a low, powerful, and relatively straight ball, often aimed at a specific area or player. The resources use different terms for this—'straight', 'flat', or 'driven'—but the principle is the same.

The 'How to Attack Corner Kicks' article also describes the tactical purpose of a straight delivery.
Read the subsection 'Straight'. Note the two specific attacking scenarios where this type of delivery is most effective.
Driven corners are perfect for two main scenarios:
- Attacking the back post: The flat trajectory allows the ball to travel over the crowd of players in the middle, aiming for a player to head it back across the face of the goal.
- Edge-of-the-box volleys: A straight, fast ball is easier for a player to strike cleanly than a curling one.
This is a specialist delivery. Data from the 2022 World Cup shows that "Direct flat" deliveries accounted for only 3.9% of all corners. It requires a specific routine and players with the technical skill to execute it.
Test your understanding!
You are preparing for an opponent whose goalkeeper struggles to command their box and is reluctant to come off their line. Which type of delivery would you prioritize in your game plan and why?
Show answer
An inswinging corner would be an excellent choice. Its trajectory curving towards the goal puts maximum pressure on a hesitant goalkeeper. By aiming the delivery into the "corridor of uncertainty" between the 6-yard box and the penalty spot, you force the keeper to make a difficult decision: stay on their line and risk being beaten by a header, or come out and risk misjudging the flight of the curling ball. This delivery directly exploits the opponent's identified weakness.
Conclusion
In this lesson, we have compared the four primary types of corner kick delivery. Understanding these principles is the first step toward designing effective set-piece routines.
Key Takeaways:
- Inswingers are high-risk, high-reward deliveries that put pressure on the goalkeeper and are ideal for attacking the near post.
- Outswingers are generally safer, allowing attackers to run onto the ball, but they also give defenders more time to organize and react.
- Short corners create unpredictability and new crossing angles by drawing defenders out of position, and are statistically very effective at creating chances.
- Driven/Flat corners are a specialist tool, used for specific routines like back-post knock-downs or shots from the edge of the area.
- There is no universally "best" delivery. The optimal choice depends on your players' strengths, your tactical goals, and the opponent's defensive weaknesses.
Preview of the Next Lesson:
Now that you understand the different ways to deliver the ball, we will move on to what the other players are doing. In our next lesson, we will begin to design attacking corner routines using a combination of zonal, man-oriented, and hybrid movements. We'll look at how player runs create and exploit the space that these deliveries are designed to attack.
