Every July, bookmakers open markets on pre-season friendlies — and every July, bettors lose money on them. Here is why pre-season football betting is almost always a losing proposition.
Why Pre-Season Results Are Unreliable
Managers Do Not Care About Results
Pre-season exists for fitness building, tactical experimentation, and giving squad players minutes. A manager who starts his strongest eleven in a friendly against a League Two side is doing his job badly. Most managers use entirely different halves with wholesale substitutions at half-time.
Squad Rotation Is Extreme
It is not unusual to see 11 changes at half-time during pre-season. The team that starts bears no resemblance to the team that finishes. This makes match result betting essentially meaningless — you are betting on two different teams playing 45 minutes each.
Fitness Over Winning
Players return from summer breaks at different fitness levels. Early pre-season is about building base fitness, not match sharpness. A team's performance in a July friendly tells you nothing about how they will perform in August with full match fitness.
The Bookmaker Margin Problem
Even if pre-season outcomes were predictable, the economics work against you. Bookmaker margins on friendlies are typically 8-10%, compared to 3-5% for competitive matches.
On a £10 bet at a typical competitive match margin of 4%, you lose roughly £0.40 to the bookmaker edge. On the same bet with a 9% pre-season margin, you lose £0.90 — more than double. Over 100 bets, this difference alone costs you £50.
Better Uses of Your Time
Instead of betting on pre-season, invest your time in:
- Transfer analysis: How do new signings change team dynamics?
- Managerial changes: New managers typically take 8-10 matches to implement their systems
- Fixture analysis: Identify early-season fixture runs that favour or challenge specific teams
- Model building: Update your prediction models with new squad data
The Exception: Season-Long Markets
While individual pre-season matches are poor bets, the pre-season period can be a good time to place season-long outright bets. Title winner, top-four, and relegation markets often offer better prices in July before the season shapes up, particularly for teams whose summer business has significantly strengthened them.
