PREDICTION RATIONALE โ€” Portugal vs Spain  (FIFA World Cup 2026, Round of 16)
Venue: Neutral site (AT&T Stadium, Arlington)

1. DATA. Last-10 internationals (Sofascore interception scraper).
   Portugal: record LWDWWWDWDW, 2.30 GF / 0.70 GA,
   xG 2.03 / xGA 0.78.
   Spain: record WDWDDWDWWW, 2.10 GF / 0.40 GA,
   xG 2.11 / xGA 0.43.
   Opponent-strength tiers (configs.MASTER_TIERS) applied per match.

2. RATINGS. Portugal atk 1.33 def 0.71; Spain atk 1.42 def 0.53.
   NEUTRAL VENUE: home boost / away penalty set to 1.0/1.0 (both teams
   travel to a host-nation site; no host advantage applies โ€” a key difference
   from the Korea/Canada/USA host-nation games). lambda Portugal 1.02, Spain 1.34
   after 90% model weight + shrink to 1.3 baseline.
   Injuries: {'Portugal': ['No major absences reported'], 'Spain': ['No major absences reported']}.
   Context: Round of 16. Iberian derby: Portugal vs Spain, the two highest-tier sides to meet so far this tournament. Talent prior reinstated (2026-07-06) โ€” near-equal tiers, so it mostly cancels here. Knockout: a draw goes to ET/pens. Neutral venue.

3. MODEL. Bivariate Poisson (lambda3 0.12). 1X2 Portugal 27.3% /
   draw 29.2% / Spain 43.5%. Winner Spain; score 1-1; fair AH Portugal +0.25.
   Over 2.5 41.8%; BTTS 48.5%.

4. EVENTS. Referee TBD: 4.2 Y + 0.13 R/match
   blended (weight 0.20) with WC base 2.6438 -> expected
   cards 2.99, P(over 3.5) 35.0%; P(any red)
   12.2%. Corners expected 8.5 (scale
   0.964) -> P(over 8.5) 48.1%.

5. LIMITATIONS. 10-match samples; hand-set tiers/priors; Poisson corners; lineups
   probable not confirmed; card base rate calibrated on only 4 WC matches.
