✍️ Match Preview

Full Analysis

Estádio Dom Afonso Henriques plays host to Guimaraes versus FC Porto in Primeira Liga, Regular Season - 18. Kick-off: Sunday 18 January 2026 at 20:30 UTC.

Current Form

Guimaraes's overall Primeira Liga record this term: 5W 2D 3L from 10 games (1.70 PPG). Last five: D W L D W. They are averaging 1.10 goals per game and conceding 1.10 — 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. This season is still relatively young for Guimaraes, so this record blends games from this season and last.

In front of their own supporters this season, Guimaraes have posted 4W 3D 3L at Estádio Dom Afonso Henriques — 1.50 PPG. At home they are averaging 1.50 goals scored and 1.50 conceded per game. Both teams have scored in 70% of their home games — an outstanding BTTS rate that is a key data point for this fixture.

FC Porto have collected 2.80 PPG across 10 Primeira Liga outings this season: 9W 1D 0L. Last five: W W W W W. They are scoring at 1.70 per game and conceding 0.30. Defensively, 0.30 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. 7 clean sheets from 10 games (70%) is an exceptional defensive record — they are keeping clean sheets more often than not. Both teams have scored in just 30% of their games, reflecting a regular tendency to keep or record clean sheets. This season is still relatively young for FC Porto, so this record blends games from this season and last.

When travelling in Primeira Liga this season, FC Porto have posted 10W 0D 0L from 10 away outings — 3.00 PPG. They are averaging 2.20 goals per away game — strong road scoring that makes them a threat even without home support. 7 away clean sheets from 10 games (70%) — they are as difficult to score against on the road as they are at home. Away from home, both teams have scored in only 30% of games — a low rate that backs BTTS No when they travel.

FC Porto arrive in superior form — a 1.10 PPG advantage (2.80 vs 1.70) that offsets much of the home-ground benefit. The away side are the form pick, with draw protection the sensible way to manage the home-field uncertainty.

H2H Analysis

The head-to-head ledger leans to FC Porto, who have claimed 7 wins from 9 meetings compared to 1 for the hosts, with 1 draws.

The 9 previous meetings have averaged 2.4 goals per game — a neutral rate that provides no strong lean on the goals market from the H2H alone. The most recent clash, on 11 Aug 2025, ended 0–3 with FC Porto winning.

It is worth noting that FC Porto have a superior record in this fixture despite their visitor status — 7 wins from 9 meetings. Home advantage alone is not a sufficient reason to dismiss that track record.

Trading

Guimaraes half-time and goal-timing data (51 games, 26 at home): they score before half-time in 69% of fixtures in home games; when goalless at HT, a second-half goal follows 79% of the time; BTTS occurs in 46% of their matches (home games); Over 2.5 goals lands in 62% of games (home games); they fail to score in 31% of games.

FC Porto half-time and goal-timing data (51 games, 26 at away): they score before half-time in 77% of fixtures in away games; when goalless at HT, a second-half goal follows 92% of the time; two or more arrive in the second half on 75% of those occasions; they lead at the break 51% of the time; BTTS occurs in 31% of their matches (away games); Over 2.5 goals lands in 50% of games (away games); they keep a clean sheet 57% of the time.

BTTS rates are mixed from the trading data — Guimaraes 39% versus FC Porto 35%; no strong lean in either direction. The over/under 2.5 picture is inconclusive from the in-play data (Guimaraes 45% | FC Porto 53%).

Poisson Model

The Poisson distribution model projects Guimaraes 0.83 xG and FC Porto 1.79 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: Guimaraes attack 1.048 / defence 1.070 | FC Porto attack 1.340 / defence 0.556. League average goals — home 1.422 / away 1.246. FC Porto's defence strength of 0.556 is below average — they are conceding at a rate that inflates the home xG figure. FC Porto have an above-average attack strength of 1.340 — the away xG of 1.79 is driven by genuine attacking quality on the road. Data: 51 Guimaraes games / 51 FC Porto games used (CurrentSeason).

Result probabilities: Guimaraes 17% | Draw 23% | FC Porto 60%. Fair-value odds: Guimaraes 5.88 | Draw 4.35 | FC Porto 1.67. The model has a clear lean to FC Porto (60%) — a 43pp gap over the next-most-likely outcome reflects a meaningful statistical advantage.

Goals markets: Over 2.5 probability 49% | BTTS probability 47% | Total xG 2.62. Over/Under 2.5 is close to a coin-flip at 49%/51% — the total xG of 2.62 sits near the 2.5 margin; this is a low-edge market from a Poisson standpoint. BTTS probability of 47% is moderate — neither team is projected to score with enough certainty to make Yes a clear standalone call.

Picks & Verdict

On the Poisson output, FC Porto are the pick at 60% — clear model lean. Current-season form corroborates the Poisson lean — partial multi-source support. Draw No Bet is worth pricing alongside the outright: 23% draw probability makes the stalemate a live outcome even at this conviction level.

On the goals line, Poisson's 2.62 combined xG gives a 49% probability to Under 2.5 — Poisson-only — limited corroboration.

The Poisson model's BTTS call is No at 47%. Form rates are neutral: Guimaraes 70% | FC Porto 30%.
