AZ vs Heerenveen: match statistics

AZ holds a slight home edge: at home they average 2.21 goals per match with an average xG of 1.77 and record 6 shots on target per game, while Heerenveen away averages 1.57 goals, xG 1.58 and 5.43 shots on target. Defensively the hosts also fare marginally better – AZ concedes 1.50 goals on average at home versus Heerenveen’s 1.71 away, and AZ’s home loss rate is only 14% compared to the visitors’ 43% loss rate on the road. However, the visitors are in excellent form over the last 5 matches: 4 wins and 1 draw, 13 goals scored and 5 conceded and 2.6 points per game, whereas AZ in their last 5 have 3 wins and 2 losses, 10 scored and 6 conceded and 1.8 points per game. AZ at home also have 0% matches without scoring, while Heerenveen fail to score in 21% of away games, which increases the hosts’ chances of consistently creating chances. Considering AZ’s higher shooting efficiency at home (conversion 14% versus Heerenveen’s 11% away) and lower tendency to lose, I tip the home win, though I expect an open game with goals.

Seasonal indicators strongly favor BTTS: AZ has BTTS at 80%, Heerenveen 64%, and the league average is 63%, suggesting both teams regularly score and concede. This season AZ scores 2.07 and concedes 1.53 per match, Heerenveen scores 1.57 and concedes 1.71; their seasonal tallies are 49 scored and 45 conceded for AZ, and 53 scored and 47 conceded for Heerenveen. xG supports this hypothesis: AZ has xG 1.85 versus average xG against Heerenveen 1.69, while Heerenveen has xG 1.58 versus average xG against AZ 1.30, indicating both teams generate and allow scoring chances. Additionally, clean sheets are rare (AZ 7%, Heerenveen 14%), and matches over 2.5 goals occur in 73% and 79% of fixtures; over2.5 combined with BTTS stands at 67% for AZ and 56% for Heerenveen, which reinforces a both-sides-scoring scenario. Considering the above and despite an unusual 'last5 BTTS' record for AZ at 0% (AZ scored 10 and conceded 6 in the last 5 games), I assess BTTS probability at 75% and 'no' at 25%, therefore the optimal pick is 'yes' (BTTS - Yes).

AZ has an xG of 1.85 and averages 2.07 goals scored per match; Heerenveen has an xG of 1.58 and averages 1.57. Comparing xG against (1.69 for Heerenveen and 1.30 for AZ) yields expected goals of 1.77 for the home side and 1.44 for the visitors (total 3.21). Season shares show AZ matches exceeded 1.5 goals in 100% of cases, and Heerenveen in 93%; for the 2.5 threshold this is 73% and 79% respectively, and in the last 5 matches over2.5 was 80% (AZ) and 100% (Heerenveen). Using a Poisson distribution with a mean of 3.21 the probability of at least 2 goals is ~83%, at least 3 goals ~62% and at least 4 goals ~40%. Combining seasonal percentages, current form and the Poisson model I set probabilities: over1.5 ≈95%, over2.5 ≈70% and over3.5 ≈42% (remaining probability for under). The strongest signal is Over 1.5 — the high season consistency 100%/93%, combined xG total of 3.21 and ~83% chance of at least 2 goals provide a clear edge for this option.

I forecast 1/1 (AZ leading at the break and winning), as the strongest signal from the data. Seasonally AZ averages 0.87 goals by half-time and has led at the break in 53% of matches, while Heerenveen averages 0.71 goals by half-time and led HT in 29% of fixtures, which favors the home side in the first 45 minutes. Over the full match AZ averages 2.07 goals with xG 1.85 versus 1.57 goals and xG 1.58 for Heerenveen, and defensively AZ concedes a lower xG against (1.30 vs 1.69 for the visitors), so the hosts have the advantage for the Full-Time result. AZ scores on average 1.2 goals in the second half versus 0.86 for Heerenveen and 73% of their matches have over 1.5 second-half goals, indicating AZ often closes out games after the break. Although Heerenveen are in excellent recent form (80% wins in the last 5 and 100% lead at the break), the seasonal HT/FT metrics and higher xG favor AZ, hence the 1/1 selection.
