Sweden vs Tunisia

The model's prior (41% Sweden win) already reflects Sweden's edge, but the key-player gap is stark: Sweden's attacking duo of Gyökeres and Isak are world-class, while Tunisia's key players are at mid-tier clubs. Tunisia's recent form is worse, and they under-perform expectations more severely than Sweden. I raise Sweden's win probability to 50% and lower Tunisia's to 23% to account for this quality differential. The draw stays near the model's level (27%) as World Cup openers can be tight. Sweden's expected goals (1.17) and Tunisia's (0.92) suggest a low-scoring match, but Sweden's attacking quality pushes the expected total slightly higher. The most likely scoreline is 1-0 (14%), followed by 2-0 (12%) as Sweden's defense (not explicitly weak) should contain Tunisia's modest attack. A 1-1 draw (11%) is plausible if Tunisia's organized defense holds, but 0-0 (10%) is less likely given Sweden's firepower.
