Full Analysis

Leo Chiangrai Stadium plays host to Chiangrai United versus Rayong FC in Thai League 1, Regular Season - 15. Kick-off: Saturday 26 December 2026 at 12:30 UTC.

Form

Chiangrai United (all games): 5W 3D 2L across 10 Thai League 1 fixtures this term — 1.80 PPG. Last five: W W D W W. They are averaging 1.30 goals per game and conceding 0.60 — a modest attacking output that tempers optimism on the Over 2.5 market. Defensively, conceding just 0.60 per game is an exceptional defensive record — one of the tightest in the division. 6 clean sheets from 10 games (60%) is a standout defensive return — they are keeping their net clean in more than half their matches. Chiangrai United have played only a handful of Thai League 1 games so far this season, so this record also draws on matches from last season.

In front of their own supporters this season, Chiangrai United have posted 4W 3D 3L at Leo Chiangrai Stadium — 1.50 PPG. At home they are averaging 0.90 goals scored and 0.90 conceded per game. 5 clean sheets from 10 home games (50%) — they are an exceptionally hard side to score against at Leo Chiangrai Stadium.

Rayong FC's overall Thai League 1 record this term: 3W 3D 4L from 10 games (1.20 PPG). Last five: D W L D W. Their scoring rate of 1.30 per game is modest, conceding 2.00 — not a side to back heavily on the Over 2.5 from their form alone. Conceding 2.00 per game is a high rate — their defensive vulnerabilities have been exposed regularly this season. 2 clean sheets from 10 outings suggests some defensive organisation. Both teams have scored in 80% of their matches this season — one of the stronger BTTS rates in the division, making Yes a well-evidenced play. Rayong FC have played only a handful of Thai League 1 games so far this season, so this record also draws on matches from last season.

Rayong FC away from home this season: 1W 2D 7L from 10 away games — 0.50 PPG on the road. Away from home they average 1.10 goals scored and 2.50 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. Their away PPG of 0.50 is notably below their overall 1.20 — form away from home has been a clear weakness this season.

The points-per-game gap of 0.60 in Chiangrai United's favour (1.80 vs 1.20) is a statistically meaningful difference. The hosts are the form pick here, with draw protection the sensible hedge given the away side's competitiveness.

Head-to-Head

Neither side has dominated this fixture. The last 4 head-to-head meetings have produced 1 wins for Chiangrai United, 2 for Rayong FC and 1 draws — an even split that leaves the H2H largely neutral as a betting input.

Historically, goals have been at a premium in this fixture — just 1.5 per game from 4 meetings. The Under 2.5 has a clear base rate from the H2H record alone. The most recent clash, on 15 Feb 2026, ended 1–1 with a draw.

With a balanced win record and just 1.5 goals per game historically, the H2H points toward a tight, low-scoring contest. Under 2.5 goals has the strongest statistical grounding from the fixture history regardless of which side wins.

Trading Data

Chiangrai United goal-timing and half-time pattern breakdown (31 games, 15 at home): they score before half-time in 73% of fixtures in home games; when goalless at HT, a second-half goal follows 71% of the time; BTTS occurs in 33% of their matches (home games); Over 2.5 goals lands in 20% of games (home games).

Rayong FC goal-timing and half-time pattern breakdown (31 games, 15 at away): they score before half-time in 73% of fixtures in away games; when goalless at HT, a second-half goal follows 100% of the time; when trailing at the break they recover to draw or win in 26% of cases; BTTS occurs in 80% of their matches (away games); Over 2.5 goals lands in 60% of games (away games).

From a combined perspective, both sides have high BTTS rates — Chiangrai United 61% and Rayong FC 74% — which reinforces the BTTS Yes angle from in-play data. The over/under 2.5 picture is inconclusive from the in-play data (Chiangrai United 32% | Rayong FC 52%).

Poisson Model

The Poisson distribution model projects Chiangrai United 1.59 xG and Rayong FC 0.87 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: Chiangrai United attack 0.911 / defence 0.808 | Rayong FC attack 0.988 / defence 1.221. League average goals — home 1.430 / away 1.091. Rayong FC bring a strong defensive rating of 1.221 — this is suppressing Chiangrai United's projected output below what their attack strength alone would suggest. Data: 31 Chiangrai United games / 31 Rayong FC games used (Blended). A blend of current and prior-season data is applied to stabilise estimates early in the campaign.

Result probabilities: Chiangrai United 54% | Draw 26% | Rayong FC 20%. Fair-value odds: Chiangrai United 1.85 | Draw 3.85 | Rayong FC 5.00. Chiangrai United hold a narrow Poisson edge at 54% — the draw (26%) is close enough to merit draw-inclusive market consideration.

Goals markets: Over 2.5 probability 45% | BTTS probability 47% | Total xG 2.46. Under 2.5 has a narrow probability edge at 55% — total xG of 2.46 is below the line but not decisively so. BTTS probability of 47% is moderate — neither team is projected to score with enough certainty to make Yes a clear standalone call.

Verdict

The Poisson model's primary lean is Chiangrai United at 54% — moderate model lean. Current-season form corroborates the Poisson lean — partial multi-source support. Draw probability of 26% warrants consideration of Double Chance or Draw No Bet on Chiangrai United if the outright odds are short.

On the goals line, Poisson's 2.46 combined xG gives a 45% probability to Under 2.5 — reasonable, supported by H2H averaging 1.5 goals per meeting.

The Poisson model's BTTS call is No at 47%. This conflicts with form data: Chiangrai United 40% | Rayong FC 80% from recent games — a notable divergence.

The Poisson model is drawing on Blended data (31 games minimum) — early-season projections carry additional uncertainty. Weight the live form and odds signals accordingly.
