Highlights

• • Away implied probability: ~87.7% vs our estimate 82% (no value)
• • Home would need >19.6% to be +EV at 5.1; we estimate ~18% (no value)

Pros

• + If the underdog wins, payout is large (5.1), but probability appears slightly below break-even
• + Conservative approach avoids overbetting on a tiny market edge with limited information

Cons

• - Favorite price is very short — bookmakers' margin likely embedded
• - Insufficient match-specific data increases model uncertainty and makes any edge fragile

Details

We see a heavy-market favorite (Away at 1.14) with an implied probability of ~87.7% and a long-priced home underdog at 5.1 (implied ~19.6%). With no external research available, we apply conservative assumptions: we estimate the true win probability for the favorite (A. Reymond/L. Sanchez) at 82% and for the underdog (H. Car/P. Tailleu) at about 18%. At those estimates the favorite's required break-even probability for the current price is 87.7% (1/1.14) — above our 82% estimate — producing a negative expected value. The underdog would need ~19.6% to justify the 5.1 price; our conservative 18% estimate falls short. Given the lack of independent information (surface, form, injuries, H2H) and the market's extremely short favorite price, we decline to recommend a side because neither price currently offers positive EV.

Key factors

• • Market heavily favors the away pair (1.14 => implied 87.7%)
• • No external data provided (surface, form, injuries, H2H) — increases uncertainty
• • Our conservative estimates (away 82% / home 18%) produce negative EV at current prices
