Football Prediction & Betting Glossary

If you're just getting into football predictions and betting, terms like "totals", "both teams to score" or "xG" can sound confusing. This glossary explains them in plain language — a quick reference you can come back to whenever you're reading a prediction on xG.Football.

xG (Expected Goals)

A metric that rates the quality of every shot on goal and adds up to how many goals a team "should" have scored given the chances it created. See the full breakdown in "What Is xG in Football".

1X2 (Home / Draw / Away)

The match-result market at the end of regulation time: a home win, a draw, or an away win. It's the most basic and most common type of football prediction and bet.

Totals (Over / Under)

A prediction on whether a chosen match metric — most often goals, but also corners, shots on target or cards — finishes above or below a set line. "Over 2.5" means a prediction of 3 or more combined goals in the match; "under" is the opposite. Lines are usually set at a half-point precisely so there's no way to land exactly on the line — for example, "Corners over 8.5" means a prediction of 9 or more corners.

Both Teams to Score (BTTS)

A prediction on whether both teams will score at least one goal during the match, regardless of the final score. It's assessed from how often each team has scored and conceded in recent matches, including head-to-head meetings.

Handicap (Spread)

A prediction with a virtual "handicap": a set number of goals is added to or subtracted from one team before comparing the final score. It's used when the gap in quality between two teams is large enough that a plain 1X2 prediction looks too predictable. European and Asian handicap lines, quarter lines and refunds are covered in a separate guide.

Odds

A number showing how much a stake multiplies if it wins, while also reflecting how likely the bookmaker considers that outcome: the lower the odds, the higher the implied probability. xG.Football shows stored bookmaker odds next to each prediction so you can compare them against the model's own statistical estimate. When the odds are higher than the true probability justifies, it is called a value bet.

Team Form

A team's results over a set number of recent matches — usually the last 5, sometimes the whole season. Form is split into overall, home and away, because many teams play noticeably better at home than on the road.

Head-to-Head (H2H)

The history of previous matches specifically between these two teams. It's a useful factor, but not a decisive one — squads and form can change a lot since the last meeting, so head-to-head is best read together with current form rather than on its own.

Prediction vs. "Prophecy" — Same Thing?

In everyday use, "prediction" and "forecast" for football are treated as synonyms. On xG.Football, both mean the same thing: a probability calculated from stored statistics, not a guess.

Football Betting: How to Use the Stats

Football betting means staking money on the outcome of an event — a match, a total, both teams to score or another market — at the bookmaker's odds. Statistics and predictions don't guarantee a result, but they support a more informed decision: compare the model's estimated probability against the bookmaker's odds, check team form and shot/corner stats, and avoid relying on the league table alone. For more on how the model's probability is calculated, see "How the xG.Football Prediction Model Works", and for reading match stats, see "How to Read Shots on Target and Corner Stats".
