West Ham United vs Arsenal: match statistics

Arsenal is the favorite in this match: they have scored 67 goals this season versus West Ham’s 42, and away they average 1.59 goals scored and only 0.88 conceded, while West Ham at home average 1.41 scored and 1.71 conceded. The quality gap is visible in xG and possession — Arsenal’s away xG is 1.54 versus the home side’s 1.24 xG, and 55% possession vs 42% gives the visitors greater control. Arsenal averages 4.76 shots on target per away match compared to West Ham’s 3.59 at home and has a much lower shutout rate (12% vs 29%), which reduces the risk of a 0-0 draw. In the last 5 matches West Ham scored 8 goals, recorded 2 wins, 2 draws and 1 loss, averaging 1.6 points per match but conceded 6 goals; Arsenal in the last 5 have 3 wins, 1 draw, 1 loss, 7 goals scored and 3 conceded and average 2.0 points per match. Considering Arsenal’s better defense (0.88 goals conceded away vs 1.71 for West Ham at home), higher xG and greater number of shots on target, the most likely outcome is an away win for Arsenal.

Based on available data I lean toward the "no" option — West Ham at home has 56% clean sheets and concedes only 0.61 goals per home game on average, so the hosts regularly limit opponents. Arsenal score 1.59 goals away on average, have 53% BTTS away and 67 goals this season (xG 1.54), but in the last 5 matches Arsenal have conceded only 3 goals (0.6 avg), indicating defensive improvement and a lower likelihood of Goal/Goal. xG confirms the disparity of chances: West Ham generate 1.85 xG while Arsenal concede 1.09 xG on average, whereas Arsenal have 1.54 xG versus 0.83 xG conceded by West Ham — this suggests West Ham will more easily create and convert chances, and Arsenal will find it harder to break down the hosts' defense. Considering seasonal BTTS 44% for West Ham, 53% for Arsenal, league BTTS level 56% and low 40% BTTS in the last 5 matches for both teams, I price BTTS at 40% for "yes" and 60% for "no", therefore I recommend a "no" bet.

The xG-and-defensive-average model yields expected goals: West Ham 1.47 (attacking xG 1.85 and opponent average xG conceded by Arsenal 1.09), Arsenal 1.19 (attacking xG 1.54 and opponent average xG conceded by West Ham 0.83), total 2.66 goals. That 2.66 total, using a Poisson distribution, implies roughly a 74–75% chance of over 1.5 goals (probability of 0–1 goals ≈25.5%), providing a strong signal for Over 1.5. Seasonal figures support this: West Ham at home has Over 1.5 in 83% of matches and scores 2.22 goals on average, Arsenal away has Over 1.5 in 65% and scores 1.59 goals, which increases the likelihood of at least two goals. The 2.5 line is borderline value (Poisson ≈49–50% for 3+ goals; season over2.5 is 61% for West Ham and 47% for Arsenal), and Over 3.5 is unlikely (~28%), therefore I recommend Over 1.5 as the best option.

West Ham led at the break in 56% of their home matches, scoring an average of 0.94 goals by half-time while conceding only 0.22, whereas Arsenal average 0.65 goals at the break on the road and concede 0.35. Over the full season West Ham score 2.22 goals per home game with an xG of 1.85 compared to Arsenal’s 1.59 goals and xG 1.54, giving the hosts an offensive edge. In the second half West Ham average 1.28 goals at home and concede just 0.39, so the team has the capacity to maintain or extend a lead after the break. On this basis the most likely scenario is 1/1 (I assign it 44% probability); alternatively I rate X/1 at 18% and X/X at 12%.
