By my reckoning, the following teams have got a result against us this year, and then gone on to sack their manager:
Leeds
Huddersfield
Cheltenham
Brighton
Yeovil
Hartlepool
Crewe
QPR
Walsall
Colchester (although he may have already gone by the time they beat us)
Amazing stat. One for the Guinness book I'd warrant.
We should broadcast this more widely, send a copy to the manager of every team we've got left to play, with a note saying "Don't beat us or you'll get the sack"
