Hunch. Palace have not yet played Spurs on 31 October, and a past coach who won the game his job was tied to stayed on.
The Sage market resolves on Crystal Palace club news: YES if before kick-off of Chelsea against Crystal Palace at 19:30 UK time on 2 December 2026 the club says Pierre Sage is no longer head coach, whether sacked, leaving by agreement or resigning, and NO if he is still in the job then. BBC Sport and Guardian reports settle it if the club page is silent, and the deadline stays 19:30 UK time on 2 December if the game moves.
We looked for cases where a football club tied the future of a head coach, in the job for less than a year, to one coming game in the middle of a season. We found six such coaches from 2017 to 2025, at clubs in England and Spain. Each time we checked whether the coach was gone within five weeks of the first press report.
