Fixture Analysis

It is a Championship clash, Regular Season - 6 as Derby welcome West Brom to Pride Park. Kick-off is set for Wednesday 9 September 2026 at 18:45 UTC.

Recent Form

Across all Championship games this season, Derby have gone 4W 1D 5L from 10 outings — a 1.30 PPG return. Last five: L L D L W. They are averaging 1.40 goals per game and conceding 1.50 — a modest attacking output that tempers optimism on the Over 2.5 market. 3 clean sheets from 10 outings provides some defensive foundation. Both teams have scored in 60% of their games — a high BTTS rate that carries real weight in the goals markets. Derby have played only a handful of Championship games so far this season, so this record also draws on matches from last season.

At home at Pride Park, Derby have gone 6W 1D 3L this season (10 games, 1.90 PPG). At home they are averaging 1.50 goals scored and 1.10 conceded per game. 4 home clean sheets from 10 games (40%) — a solid defensive base on their own ground. Their home PPG of 1.90 is noticeably stronger than their overall 1.30 — Derby are significantly better at Pride Park than their overall form suggests.

West Brom — All Games: 4W 4D 2L from 10 Championship fixtures this season — 1.60 PPG. Last five: L W W L D. Their scoring rate of 1.30 per game is modest, conceding 0.80 — not a side to back heavily on the Over 2.5 from their form alone. Defensively, 0.80 goals conceded per game is elite-level — a side this difficult to score against is a real threat to Over 2.5 and BTTS Yes. 5 clean sheets from 10 games (50%) is an exceptional defensive record — they are keeping clean sheets more often than not. West Brom have played only a handful of Championship games so far this season, so this record also draws on matches from last season.

West Brom away from home this season: 3W 3D 4L from 10 away games — 1.20 PPG on the road. Away from home they average 0.90 goals scored and 1.20 conceded per game. 4 clean sheets from 10 away games (40%) shows they are capable of shutting up shop on the road.

The form comparison is too close to call — 1.30 PPG (Derby) versus 1.60 (West Brom). When the figures are this level, no pick can be reliably derived from recent results alone.

Head to Head

The historical ledger comes down firmly in favour of Derby: 4 wins from 6 previous clashes against 0 for West Brom, with 2 draws across those contests.

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 23 Jan 2026, ended 1–1 with a draw.

The historical record gives Derby a meaningful edge here — 4 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.

Trading Patterns

Derby in-play and half-time data (50 games, 25 at home): they score before half-time in 80% of fixtures in home 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 (home games); Over 2.5 goals lands in 44% of games (home games).

West Brom in-play and half-time data (50 games, 25 at away): they score before half-time in 68% of fixtures in away games; when goalless at HT, a second-half goal follows 62% of the time; BTTS occurs in 52% of their matches (away games); Over 2.5 goals lands in 52% of games (away games); they fail to score in 30% of games.

BTTS rates are mixed from the trading data — Derby 64% versus West Brom 54%; no strong lean in either direction. The over/under 2.5 picture is inconclusive from the in-play data (Derby 54% | West Brom 48%).

Poisson Model

The Poisson distribution model projects Derby 1.35 xG and West Brom 1.50 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: Derby attack 0.903 / defence 1.185 | West Brom attack 0.971 / defence 1.047. League average goals — home 1.431 / away 1.305. Data: 50 Derby games / 50 West Brom games used (CurrentSeason).

Result probabilities: Derby 31% | Draw 31% | West Brom 38%. Fair-value odds: Derby 3.23 | Draw 3.23 | West Brom 2.63. This is a low-confidence result — no outcome exceeds 45%. The draw at 31% is a primary outcome, not an afterthought.

Goals markets: Over 2.5 probability 54% | BTTS probability 61% | Total xG 2.86. Over/Under 2.5 is close to a coin-flip at 54%/46% — the total xG of 2.86 sits near the 2.5 margin; this is a low-edge market from a Poisson standpoint. BTTS Yes at 61% reflects that both xG figures (1.35 / 1.50) are above the threshold where scoring blanks become the primary outcome — both sides are projected to find the net.

Summary & Verdict

The Poisson model's primary lean is West Brom at 38% — marginal model lean. With a 31% draw probability, Draw No Bet on West Brom offers a more defensible entry point than the straight win. The opposing side holds a 31% win probability per the model — this is not a banker and should be staked accordingly.

The Poisson model projects 2.86 xG in total — Over 2.5 at 54% — Poisson-only — limited corroboration confidence — though H2H averaging only 1.8 goals per meeting points in the other direction.

On the BTTS market, Poisson puts 61% on Yes. Form rates are neutral: Derby 50% | West Brom 50%.

The outsider holds a 31% 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.
