What Are Attack Power and Defense Power?
Attack Power and Defense Power are two proprietary metrics developed by OddsWiki's AI team to quantify how strong a football team is in attack and how resilient they are defensively.
These ratings appear in OddsWiki's match forecasts as normalised scores, typically ranging from 0 to 100 or in a relative format (e.g., "Attack Power: 78 — above league average").
- Attack Power (attPower) — Measures a team's ability to create and convert goal-scoring opportunities, factoring in shot volume, shot quality (xGoals), conversion rate, and the defensive strength of past opponents.
- Defense Power (defPower) — Measures a team's ability to prevent opponents from creating and converting chances, factoring in goals conceded, xG conceded, press intensity, and the attacking strength of past opponents.
Together, they form the foundation of OddsWiki's match outcome probability model.
How Are These Metrics Calculated?
Our AI model calculates Attack Power and Defense Power using a rolling weighted average of recent match data (typically the last 6–10 games), with adjustments for:
Attack Power calculation inputs: - Goals scored per 90 minutes - xGoals generated per 90 minutes (chance quality, not just volume) - Shots on target rate - Opponent Defense Power (strength of schedule adjustment) - Home vs. away performance split
Defense Power calculation inputs: - Goals conceded per 90 minutes - xGoals conceded per 90 minutes - Press intensity and high-press recovery rate - Opponent Attack Power faced - Clean sheet percentage
This produces a strength-of-schedule-adjusted rating that more accurately reflects a team's true quality than raw goals-for / goals-against statistics.
How to Interpret Attack Power and Defense Power
When you open an upcoming match on OddsWiki, you'll see Attack Power and Defense Power displayed for both teams. Here's how to read them:
Identifying mismatches: If Team A has Attack Power 82 vs. Team B's Defense Power 41, this is a significant mismatch — OddsWiki's model will predict a higher probability of goals and a Team A win.
Close matchups: When Attack Power and Defense Power are close for both teams, the model predicts a competitive, lower-scoring game — potentially flagging a "Draw" or "Under 2.5 Goals" opportunity.
Form trends: Attack Power and Defense Power update after every match round. A team improving their Attack Power over 3+ consecutive weeks is a positive momentum signal.
Why These Metrics Matter for Betting
Bookmakers primarily price markets based on historical results and market flow. OddsWiki's Attack Power and Defense Power metrics provide an independent assessment of underlying quality that can diverge from bookmaker pricing.
Scenarios where this creates betting value:
- A team with high Attack Power is priced as an underdog because they recently lost a close match with 2.1 xGoals vs 0.2 xGoals conceded (bad luck, not bad form).
- A team with declining Defense Power is still priced as a favourite because they're on a winning run fuelled by strong goalkeeping.
- An away team has higher Attack Power than the home favourite, but the home crowd premium inflates the home team's price.
In each case, comparing OddsWiki's metrics against bookmaker odds reveals potential value.
Frequently Asked Questions: Attack Power & Defense Power
Are Attack Power and Defense Power available for all leagues?
OddsWiki's Attack Power and Defense Power metrics are available for the top football leagues covered by our prediction engine, including Premier League, La Liga, Bundesliga, Serie A, Ligue 1, Champions League, and more. Coverage expands regularly.
How often do Attack Power and Defense Power update?
These metrics update after each completed match round. In leagues with midweek fixtures, ratings can update twice weekly.
What is a good Attack Power score?
Attack Power scores are relative to the league average. A score significantly above average (e.g., 70+ on a 0–100 scale) indicates a team in the top third of attacking output in their league. The exact thresholds vary by competition.
Do Attack Power and Defense Power replace traditional stats?
No — they complement traditional statistics. OddsWiki's metrics provide a single comparable number that synthesises multiple underlying stats. We encourage users to also review xGoals, form guides, and H2H history alongside these ratings.
How are OddsWiki's metrics different from other football data providers?
Most publicly available metrics (goals, assists, shots) don't adjust for opponent quality. OddsWiki's Attack Power and Defense Power are strength-of-schedule adjusted, meaning a team with 2.0 xGoals against a weak defence scores differently than 2.0 xGoals against an elite defence.
