Mainz's recent record: It is necessary to analyze its goal loss data in the last 5-6 games in all competitions, especially its offensive efficiency and defensive solidity, to evaluate its goal-scoring ability and tendency to concede. St. Pauli's recent performance: It is necessary to examine their recent performance as a promoted or mid-table team in the league, focusing on their away attacking firepower and defensive resilience.

are for Under 2.5 goals and the current odds combination is 0.99 (under) vs 0.76 (over). This set of odds shows that the market expects a preference for total goals over 2.5 (lower odds), while options under 2.5 goals have higher returns but are not widely favored. It is necessary to combine the fundamentals to analyze whether this odds positioning truly reflects the offensive and defensive situation of both sides, or whether there is a market bias.

Based on the above analysis: 1. Combined with recent form: If both teams show weak offensive or excellent defense, support the direction of the small ball. 2. Combined with historical confrontations: If past matchups are mostly stalemate and low scores, it will enhance the confidence of the small ball. 3. Combine the odds: Although the market is slightly bullish on the over-ball, there may be value opportunities for the high-paying small ball option. The final prediction should clearly indicate whether the total number of goals in the game is likely to be under 2.5 goals, and a brief logical assessment of the user's probability of an "away win" to determine whether it is compatible with the under-goal trend (e.g., an away team's 1-0 win or 1-1 draw is a small goal).

on this part is a risk warning. It is necessary to point out the risk points that may overturn the "under 2.5 goals" prediction, such as obvious holes in the recent defenses of both teams, the return of key attackers, the majority of historical head-to-head over-goals, or the subsequent drastic changes in odds in favor of over-balls. It is emphasized that when information is incomplete or contradictory, choosing to wait and see is a rational strategy.
