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): 4W 2D 4L across 10 Thai League 1 fixtures this term — 1.40 PPG. Last five: D L L L L. They are averaging 0.80 goals per game and conceding 0.80 — a modest attacking output that tempers optimism on the Over 2.5 market. Defensively, conceding just 0.80 per game is an exceptional defensive record — one of the tightest in the division. 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. 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 2D 4L at Leo Chiangrai Stadium — 1.40 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 L D L L. Their scoring rate of 1.40 per game is modest, conceding 2.20 — not a side to back heavily on the Over 2.5 from their form alone. Conceding 2.20 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 70% of their games — a noteworthy BTTS rate that supports the Yes market. 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 0D 9L from 10 away games — 0.30 PPG on the road. Away from home they average 1.10 goals scored and 3.00 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 0.30 is notably below their overall 1.20 — form away from home has been a clear weakness this season.

A near-identical PPG reading — 1.40 for Chiangrai United, 1.20 for Rayong FC — means the form record is uninstructive on result selection. The goals and market sections will carry greater evidential weight.

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 (36 games, 17 at home): they score before half-time in 71% of fixtures in home games; when goalless at HT, a second-half goal follows 78% of the time; BTTS occurs in 35% of their matches (home games); Over 2.5 goals lands in 24% of games (home games).

Rayong FC goal-timing and half-time pattern breakdown (36 games, 17 at away): they score before half-time in 82% 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 25% of cases; BTTS occurs in 82% of their matches (away games); Over 2.5 goals lands in 65% of games (away games).

From a combined perspective, both sides have high BTTS rates — Chiangrai United 61% and Rayong FC 75% — 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 33% | Rayong FC 53%).

Poisson Model

The Poisson distribution model projects Chiangrai United 1.62 xG and Rayong FC 1.32 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 0.794 / defence 0.848 | Rayong FC attack 1.069 / defence 1.416. League average goals — home 1.445 / away 1.456. Chiangrai United's attack strength of 0.794 is below the league average — the 1.62 xG projection reflects a team that scores at a discount to the division norm. Rayong FC bring a strong defensive rating of 1.416 — this is suppressing Chiangrai United's projected output below what their attack strength alone would suggest. Data: 36 Chiangrai United games / 37 Rayong FC games used (CurrentSeason).

Result probabilities: Chiangrai United 44% | Draw 26% | Rayong FC 30%. Fair-value odds: Chiangrai United 2.27 | Draw 3.85 | Rayong FC 3.33. This is a low-confidence result — no outcome exceeds 45%. The draw at 26% is a primary outcome, not an afterthought.

Goals markets: Over 2.5 probability 56% | BTTS probability 60% | Total xG 2.94. Over 2.5 holds a meaningful probability edge at 56% — the 2.94 total xG provides moderate support, though the model is not projecting a high-scoring game. BTTS Yes at 60% reflects that both xG figures (1.62 / 1.32) are above the threshold where scoring blanks become the primary outcome — both sides are projected to find the net.

Verdict

The Poisson model's primary lean is Chiangrai United at 44% — marginal model lean. Draw probability of 26% warrants consideration of Double Chance or Draw No Bet on Chiangrai United if the outright odds are short. The opposing side holds a 30% win probability per the model — this is not a banker and should be staked accordingly.

On the goals line, Poisson's 2.94 combined xG gives a 56% probability to Over 2.5 — marginal — conflicting signals, supported by form averaging 2.9 goals per game — though H2H averaging only 1.5 goals per meeting points in the other direction.

The Poisson model's BTTS call is Yes at 60%. Form rates corroborate: Chiangrai United 40% | Rayong FC 80% BTTS from recent games.

The outsider holds a 30% 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.
