Ethnikos Achna vs Olympiakos: match statistics

I predict a win for Ethnikos Achna: the hosts win 50% of home matches and have a positive goal differential at the stadium (+2), averaging 1.14 goals scored and 1.00 conceded per game. Olympiakos win only 27% of away fixtures, have a negative away goal differential (-8) and average 0.87 goals scored and 1.4 conceded per away match, which limits their effectiveness on the road. Ethnikos is also more efficient in finishing — 13% conversion versus 10% for the visitors and 3.5 shots on target per game vs 3.2 for the guests — despite similar average xG (1.14 vs 1.18), so the hosts finish chances better. There is, however, a risk of a low-scoring outcome: the hosts failed to score in 50% of home games, and the visitors in 40% of away matches; in the last 5 matches Ethnikos average 0.8 points per game versus 1.2 for Olympiakos, meaning the visitors have slightly better form. Considering the hosts’ home performance and finishing efficiency, I assign a 52% probability to an Ethnikos win, 20% to a draw and 28% to an Olympiakos victory.

Although both teams score few goals this season (Ethnikos 0.86, Olympiakos 0.87 per match), their defenses concede on average 1.36 and 1.40 goals per match respectively, which increases the likelihood of both teams scoring. In the last 5 matches both sides have been conceding even more — on average 1.6 (Ethnikos) and 1.8 (Olympiakos) goals — and the BTTS rate in the last 5 matches is 60% for Ethnikos and 40% for Olympiakos. xG confirms that both sides create chances: season xG is 1.14 (Ethnikos) and 1.18 (Olympiakos), and in the last 5 rounds xG is 1.19 and 1.30, which suggests a real possibility of goals from both teams. Additionally, clean sheets are rare — season percentages are 29% and 27% — and the league average goals of 2.59 with a season BTTS of 41% supports the both-teams-to-score scenario. On this basis I select BTTS = Yes (65% vs 35%), because the numbers indicate both teams more often create chances and concede goals than keep a clean sheet.

Combining xG values, Ethnikos Achna has an expected 1.31 xG (1.14 xG_for vs 1.48 xG_against of the opponent), and Olympiakos 1.36 xG (1.18 vs 1.54), yielding a total of 2.67 expected goals. At this total the Poisson distribution indicates a probability of over 1.5 goals at around 75% (exactly ~74.6%), over 2.5 at about 50% and over 3.5 at about 28%. Seasonal metrics support the forecast: the percentage of matches above 1.5 is 71% for Ethnikos and 67% for Olympiakos, and the league averages 2.59 goals per match. Both teams have high xG_against values (1.54 and 1.48) and a large number of goals conceded this season (48 and 40), which increases the risk of goals from both sides. As a result, the strongest signal from the data is a bet on Over 1.5.

I project a Half-Time/Full-Time draw/draw (X/X) as the most likely scenario. The home side have been level at the break in 50% of their home matches, while the visitors have been level at half-time in 33% of their away fixtures, yielding an estimated probability of a draw at the break of approximately 41%. Over the full match the home team record draws in 43% of games at home and the visitors 27% on the road. Both teams display similar expected goals values: 1.14 (Ethnikos) versus 1.18 (Olympiakos), with comparable xG conceded figures of 1.54 vs 1.48, so the quality gap should be minimal. The visitors average 3.2 shots on target per game against the hosts’ 2.5, but the home side show stronger first-half metrics (scoredAVGHT 0.5 and 86% clean halves HT at home), indicating a conservative first half and a draw-paced match.
