- Outside view: most established players under long contracts at top clubs remain in place in any given short pre-deadline window unless an advanced transfer saga is already visible.
- Inside view: the settlement is asymmetric toward Chelsea because any non-transfer, including no deal, injury, failed medical, or simple retention, resolves to Chelsea; an exit requires club agreement, a very large fee, player terms, and official announcement within roughly five days. I treat contract length, age profile, and deadline mechanics as signal; unspecified dressing-room or trophy narratives as weak signal.
- Divergence: after forming the estimate independently, the 13.7% implied probability implies an ~86% chance of a new team/Other resolution within days, which looks like low-liquidity mispricing or option confusion rather than information unless there is confirmed 2026 news not included here.
What would change it: A credible report that Chelsea have accepted a bid or Enzo has agreed terms/submitted a formal transfer request before Sep. 1 would sharply lower this estimate.
