Analysis & Preview

A Championship encounter, Regular Season - 13 sees Derby travel to The Den to take on Millwall. The game is scheduled for Saturday 31 October 2026, 15:00 UTC.

Form Guide

Millwall — All Games: 5W 2D 3L from 10 Championship outings this season, averaging 1.70 points per game. Last five: L W W L L. They are averaging 1.40 goals per game and conceding 1.20 — a modest attacking output that tempers optimism on the Over 2.5 market. 5 clean sheets from 10 games (50%) is a standout defensive return — they are keeping their net clean in more than half their matches. Both teams have scored in just 30% of their matches, indicating a tendency toward clean sheets or low-scoring outcomes. Millwall have played only a handful of Championship games so far this season, so this record also draws on matches from last season.

Millwall's home record at The Den: 5W 0D 5L from 10 Championship appearances (1.50 PPG). At home they are averaging 1.40 goals scored and 1.20 conceded per game. 5 clean sheets from 10 home games (50%) — they are an exceptionally hard side to score against at The Den. At home, both teams have scored in only 30% of games — reinforcing BTTS No as the home-venue-backed angle.

Looking at all fixtures this season, Derby stand at 4W 1D 5L from 10 Championship matches — 1.30 PPG. Last five: L L D L W. Their scoring rate of 1.40 per game is modest, conceding 1.50 — not a side to back heavily on the Over 2.5 from their form alone. 3 clean sheets from 10 outings suggests some defensive organisation. Both teams have scored in 60% of their games — a noteworthy BTTS rate that supports the Yes market. Derby have played only a handful of Championship games so far this season, so this record also draws on matches from last season.

When travelling in Championship this season, Derby have posted 3W 0D 7L from 10 away outings — 0.90 PPG. Away from home they average 1.30 goals scored and 1.80 conceded per game. BTTS has landed in 60% of their away games — meaningful support for the Yes angle in this specific context.

The form figures are too closely matched to derive a directional pick: Millwall 1.70 PPG, Derby 1.30 PPG. Look to other data sets to build the analysis.

H2H Record

The fixture history tells a clear story: Millwall have dominated this rivalry, winning 3 of 6 past contests while Derby have managed just 0 wins.

The 6 previous meetings have averaged 1.8 goals per game — a neutral rate that provides no strong lean on the goals market from the H2H alone. The most recent clash, on 10 Mar 2026, ended 1–0 with Millwall winning.

The historical record gives Millwall a meaningful edge here — 3 wins from 6 meetings is the kind of ledger that should not be discounted when the form picture is inconclusive. Even away from home, the visitors have struggled to impose themselves in this fixture.

In-Play Data

Millwall trading profile (50 games, 25 at home): they score before half-time in 68% of fixtures in home games; when goalless at HT, a second-half goal follows 76% of the time; two or more arrive in the second half on 65% of those occasions; BTTS occurs in 36% of their matches (home games); Over 2.5 goals lands in 52% of games (home games); they keep a clean sheet 42% of the time.

Derby trading profile (50 games, 25 at away): they score before half-time in 84% of fixtures in away games; when goalless at HT, a second-half goal follows 100% of the time; two or more arrive in the second half on 56% of those occasions; BTTS occurs in 64% of their matches (away games); Over 2.5 goals lands in 64% of games (away games).

BTTS rates are mixed from the trading data — Millwall 46% versus Derby 64%; no strong lean in either direction. The over/under 2.5 picture is inconclusive from the in-play data (Millwall 46% | Derby 54%).

Poisson Model

The Poisson distribution model projects Millwall 1.44 xG and Derby 1.44 xG. These expected goals figures are the primary input: they feed a goal-probability matrix across all scoreline combinations to derive the result and market probabilities below. Underlying strength ratings: Millwall attack 1.056 / defence 1.013 | Derby attack 1.092 / defence 0.953. League average goals — home 1.431 / away 1.305. Data: 50 Millwall games / 50 Derby games used (CurrentSeason).

Result probabilities: Millwall 34% | Draw 31% | Derby 34%. Fair-value odds: Millwall 2.94 | Draw 3.23 | Derby 2.94. The draw (31%) is the Poisson-preferred outcome — neither side is more likely to win than to draw, making draw-inclusive markets the most model-aligned approach.

Goals markets: Over 2.5 probability 55% | BTTS probability 61% | Total xG 2.88. Over 2.5 holds a meaningful probability edge at 55% — the 2.88 total xG provides moderate support, though the model is not projecting a high-scoring game. BTTS Yes at 61% reflects that both xG figures (1.44 / 1.44) are above the threshold where scoring blanks become the primary outcome — both sides are projected to find the net.

Analysis Verdict

The Poisson model's preferred outcome is the draw at 31% — neither side is more likely to win than to draw. Draw-inclusive markets are the most model-aligned approach. Home win at 34% and away win at 34% are close enough that backing either outright carries significant draw exposure.

On the goals line, Poisson's 2.88 combined xG gives a 55% probability to Over 2.5 — marginal — conflicting signals, supported by form averaging 2.9 goals per game — though H2H averaging only 1.8 goals per meeting points in the other direction.

Poisson assigns a 61% probability to BTTS Yes based on the attack/defence strength model. Form rates are neutral: Millwall 30% | Derby 60%.

The outsider holds a 34% win probability per the model — this is not a banker and should not be treated as one. Proportionate stakes are appropriate given the genuine contest the data projects.
