Navigating the world of football analytics can be challenging. At CAUHOI2025.UK.COM, we aim to provide clarity and expertise. This article answers the question of what aerial battles are in football, and dives into their significance and evaluation in modern football analysis.
What Is an Aerial Battle in Football?
An aerial battle in football, also known as an aerial duel, occurs when two players compete for a ball in the air. This situation is symmetrical because neither player initially has possession. Aerial duels are a key component of football, requiring players to exhibit strength, timing, and technique to win possession.
Defining Aerial Duels in Football
Aerial duels are distinct from ground duels, where one player typically has possession and the other tries to regain it. According to Opta, a leading sports data provider, aerial duels are recognized as a specific type of 1v1 event within the broader category of duels. These contests are pivotal in various areas of the pitch, influencing both defensive and offensive plays.
The Significance of Aerial Battles
Aerial battles are more than just physical contests; they are strategic plays that can significantly impact the flow and outcome of a match. Winning aerial duels can lead to:
- Gaining Possession: Securing the ball in advantageous positions.
- Defensive Clearances: Preventing the opposition from creating scoring opportunities.
- Creating Scoring Chances: Setting up opportunities for teammates to score.
Why Are Aerial Battles Important?
Aerial battles are crucial because they directly correlate with a team’s success. Teams that dominate in the air often control the game’s tempo and have a higher likelihood of winning.
Correlation with Match Outcomes
Teams that win more aerial duels have a statistically higher chance of winning matches. According to research, a team winning in aerial duels has a 39.2% chance of winning the match, while a team losing has only a 32.6% chance. This highlights the importance of aerial supremacy in securing victories.
Impact on Scoring Opportunities
Aerial duels frequently lead to scoring opportunities. In recent Premier League seasons, approximately 29% of goals were scored within 10 seconds of winning a fair duel. When including goals from fouls resulting from 1v1 situations (free kicks or penalties), this number jumps to 39%. This demonstrates the direct link between winning duels and creating goal-scoring chances.
Where Do Aerial Battles Occur Most Often?
The location on the pitch significantly influences the outcome and importance of aerial duels. Generally, players closer to their own goal are more likely to win duels.
Defensive vs. Offensive Zones
Defenders typically have the upper hand in aerial duels near their own goal. This is because their primary role is to dispossess the attacker and thwart the attack. In contrast, attackers specialize in shooting and need to be more creative to overcome the defender’s advantage.
Duel Success Rate and Distance from Goal
The probability of winning a duel increases the closer the player is to their own goal. This advantage is mainly for the defending team, as they are focused on preventing the attacker from advancing.
How Are Aerial Battle Abilities Evaluated?
Evaluating a player’s aerial battle ability involves more than just a simple win percentage. Advanced models, like the Bradley-Terry model, provide a more nuanced assessment by considering the strength of the opponents faced.
Traditional Assessment: Duel Success Rate
The traditional method of assessing aerial duel abilities is based on the duel success rate:
Duel Success Rate = (Number of Duels Won / Total Number of Duels) x 100%
While straightforward, this method has limitations. It doesn’t account for the quality of the opponents a player faces. Facing weaker opponents can inflate a player’s success rate, while consistently challenging top players can deflate it.
Advanced Assessment: The Bradley-Terry Model
The Bradley-Terry model offers a more sophisticated evaluation by explicitly modeling opponent ability. This model adjusts a player’s rating based on the quality of the opponents they face.
How the Bradley-Terry Model Works
For a 1v1 contest between two players i and j, the probability of player i winning is expressed as:
P(i wins against j) = λi / (λi + λj)
Here, λ represents the ability of each player. The model estimates these abilities based on the results of multiple encounters, providing a more accurate representation of a player’s true skill.
Advantages of the Bradley-Terry Model
- Accounts for Opponent Ability: Adjusts player ratings based on the strength of the opposition.
- Predictive Power: Can estimate the outcome of contests between players who haven’t faced each other before.
How Does the Bradley-Terry Model Compare to Duel Success Rates?
While there is a strong correlation between Bradley-Terry ratings and duel success rates, notable differences exist. The correlation for aerial duels is around 0.94, and for ground duels, it’s about 0.86. These differences highlight how the Bradley-Terry model refines player evaluations.
Practical Examples of Differing Evaluations
Consider the following examples from a study of the 2015/16, 2016/17, and part of the 2017/18 Premier League seasons:
- Peter Crouch: Ranked 15th in duel success rate but 4th in Bradley-Terry ability.
- Andy Carroll: Ranked 44th in duel success rate but 11th in Bradley-Terry ability.
- Phil Jones: Ranked 6th in duel success rate but 20th in Bradley-Terry ability.
These discrepancies show that the Bradley-Terry model can reveal hidden strengths and weaknesses not apparent in simple success rates.

How Can This Knowledge Be Applied?
Understanding aerial battle dynamics and using advanced evaluation methods can significantly enhance team strategy and player recruitment.
Implications for Recruiting
Duel success rates can be misleading when evaluating a player’s 1v1 ability. The Bradley-Terry model provides a more accurate assessment, helping clubs identify undervalued or overvalued players.
Match Planning and Team Selection
Bradley-Terry scores can predict the outcome of specific matchups, allowing coaches to:
- Assign marking responsibilities to neutralize opposition attackers.
- Exploit 1v1 weaknesses in the opposition defense.
- Strategically position players during set-piece situations to increase the chances of winning the ball.
