Where our probabilities disagree with bookmaker prices.
| Market | Our model | Bookies imply | Difference |
|---|---|---|---|
| Over 2.5 Goals | 37.3% | 51.5% | 14 pts under |
| Both Teams to Score | 48.6% | 57.8% | 9 pts under |
| Charlton Win | 31.5% | 40.0% | 8 pts under |
What this means: where our model sits above the bookies is where we see value they don't; below means the market already has it priced, no edge there.
The model makes Derby 41% favourites here. Charlton carry the 32% upset.
Charlton have taken 7 points from their last five; Derby have lost their last two. Form gives little away going into this Championship tie.
A razor-thin margin: Derby at 41%, but the draw sits at 28%. Covering two of the three results is the sensible approach when the margins are this fine.
The bookmakers have priced this match fairly. Our model doesn't see a big edge in the match result market.
xG explained: Expected Goals measures chance quality. 1.5 xG = a side typically converts those chances into 1.5 goals. Outscoring xG = running hot, possible regression risk.
Charlton create chances worth 1.2 a game (and give up chances worth 1.6), leaving them -0.4 a game on the balance. Derby create 1.4 (giving up 1.4) for a balance of +0.1. On the quality of chances, Derby look the stronger side. they create more and give up less.
Charlton average 1.6 goals per game and Derby manage 1.4. Combined that's just 3.0. We make it only 37% for three or more, so the lean is towards a lower-scoring game. Whether both teams score is a genuine coin-flip, and we make it 49%.
Both teams score in 52% of Charlton's home games and 65% of Derby's away matches. both teams finding the net isn't guaranteed.
