Pre-Match Analysis
Chesterfield and Grimsby meet at SMH Group Stadium in League Two, Regular Season - 19. This fixture gets under way on Saturday 12 December 2026 at 12:30 UTC.
Form & Momentum
Chesterfield have collected 1.50 PPG across 10 League Two outings this season: 4W 3D 3L. Last five: W L W D L. Offensively they are averaging 1.70 goals per game, with 1.40 conceded. 2 clean sheets from 10 outings provides some defensive foundation. Both teams have scored in 70% of their games — a high BTTS rate that carries real weight in the goals markets. This season is still relatively young for Chesterfield, so this record blends games from this season and last.
In front of their own supporters this season, Chesterfield have posted 5W 3D 2L at SMH Group Stadium — 1.80 PPG. At home they are averaging 1.60 goals scored and 1.00 conceded per game.
Grimsby's overall League Two record this term: 2W 4D 4L from 10 games (1.00 PPG). Last five: W L L L L. Their scoring rate of 1.20 per game is modest, conceding 1.30 — 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. This season is still relatively young for Grimsby, so this record blends games from this season and last.
When travelling in League Two this season, Grimsby have posted 2W 5D 3L from 10 away outings — 1.10 PPG. Away from home they average 1.50 goals scored and 1.40 conceded per game. Both teams have scored in 80% of their away matches — a high BTTS rate on the road that directly informs this fixture.
The points-per-game gap of 0.50 in Chesterfield's favour (1.50 vs 1.00) is a statistically meaningful difference. The hosts are the form pick here, with draw protection the sensible hedge given the away side's competitiveness.
H2H History
Across 4 previous meetings, Chesterfield are the stronger side on paper — 3 victories to 0, with 1 draws in between.
The 4 previous meetings have averaged 2.2 goals per game — a neutral rate that provides no strong lean on the goals market from the H2H alone. The most recent clash, on 14 Apr 2026, ended 2–1 with Chesterfield winning.
The historical record gives Chesterfield a meaningful edge here — 3 wins from 4 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
Chesterfield half-time and goal-timing data (59 games, 29 at home): they score before half-time in 86% of fixtures in home games; when goalless at HT, a second-half goal follows 86% of the time; BTTS occurs in 55% of their matches (home games); Over 2.5 goals lands in 45% of games (home games).
Grimsby half-time and goal-timing data (59 games, 29 at away): they score before half-time in 69% of fixtures in away games; when goalless at HT, a second-half goal follows 82% of the time; BTTS occurs in 55% of their matches (away games); Over 2.5 goals lands in 48% of games (away games).
BTTS rates are mixed from the trading data — Chesterfield 59% versus Grimsby 51%; no strong lean in either direction. The over/under 2.5 picture is inconclusive from the in-play data (Chesterfield 46% | Grimsby 49%).
Poisson Model
The Poisson distribution model projects Chesterfield 1.68 xG and Grimsby 1.14 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: Chesterfield attack 1.232 / defence 1.091 | Grimsby attack 1.023 / defence 1.006. League average goals — home 1.358 / away 1.019. Data: 57 Chesterfield games / 57 Grimsby games used (CurrentSeason).
Result probabilities: Chesterfield 48% | Draw 28% | Grimsby 24%. Fair-value odds: Chesterfield 2.08 | Draw 3.57 | Grimsby 4.17. Chesterfield hold a narrow Poisson edge at 48% — the draw (28%) is close enough to merit draw-inclusive market consideration.
Goals markets: Over 2.5 probability 54% | BTTS probability 57% | Total xG 2.82. Over/Under 2.5 is close to a coin-flip at 54%/46% — the total xG of 2.82 sits near the 2.5 margin; this is a low-edge market from a Poisson standpoint. BTTS probability of 57% is moderate — neither team is projected to score with enough certainty to make Yes a clear standalone call.
Final Verdict
Poisson rates Chesterfield as the most likely outcome at 48% — moderate model lean. Current-season form corroborates the Poisson lean — partial multi-source support. Draw probability of 28% warrants consideration of Double Chance or Draw No Bet on Chesterfield if the outright odds are short.
The Poisson model projects 2.82 xG in total — Over 2.5 at 54% — reasonable confidence, supported by form averaging 2.8 goals per game.
Poisson assigns a 57% probability to BTTS Yes based on the attack/defence strength model. Form rates corroborate: Chesterfield 50% | Grimsby 80% BTTS from recent games.
