In a Nutshell
When the ball is kicked high into the air, players from both teams jump to head it. This signal tracks how good a team is at winning those mid-air battles. It measures two things: how often they win when they go up for a header, and how often they get involved in these duels in the first place. A team that wins most of their aerial contests has a real advantage because they can better control the game when the ball is in the air.
Why It Matters
Aerial ability influences set pieces, crosses, goal kicks, and defensive clearances. A team that dominates in the air is harder to attack with long balls and creates more second-ball opportunities from headers.
How It's Calculated
Data Sources
Aerial duel statistics (won and lost) from match data, aggregated across recent matches in the same competition.
Key Formula
Primarily looks at how often a team wins contested headers, with a secondary measure of how frequently they get involved in aerial battles. Win rate is the main factor because it directly shows heading quality, while volume indicates how often the team seeks out aerial contests.
Normalization
Teams are compared against the full range seen across all leagues, from the weakest to the most dominant in the air. The combined score reflects both the quality and frequency of aerial success.
Confidence Impact
Requires at least 5 matches with aerial data for both teams. Uncertainty starts high with minimal data and drops to its lowest level with 15+ matches. Additional penalties apply when data is incomplete or older than 14 days. With fewer than 5 matches, this signal is excluded entirely.

Premier League — Dec 2025
What happened: The signal leaned slightly toward Villa, but Arsenal's strengths in other signals offset this. This illustrates why no single signal tells the full story — context from all signals matters.

Myth: "Winning headers is just about height and physicality"
Reality: Aerial dominance depends as much on timing, positioning, and coaching as on physical attributes. Teams with well-drilled set-piece routines and intelligent movement can dominate aerially without being stereotypically "physical."
Myth: "Lots of aerial duels means a team is good in the air"
Reality: High volume without a high win rate means a team is contesting headers but losing them. A side with 40 aerial duels per match but only a 42% win rate is actually losing more than it wins. Win rate is the primary component because quality matters more than quantity.
Myth: "Aerial dominance only matters at set pieces"
Reality: Aerial duels happen across the entire pitch: goal kicks, long clearances, crosses into the box, and midfield battles for second balls. Teams strong in the air control transitions and territory, not just corners and free kicks.
Advanced Insights
What This Signal Cannot Tell You
- No single signal determines match outcome
- All signals carry uncertainty that widens probability ranges
- Data freshness affects confidence in the assessment
- Context matters: signals interact with each other and with match circumstances
The Bottom Line
Aerial Dominance measures how often and how effectively a team wins contested headers across the pitch. Use it alongside other signals for a balanced view of the match.
