No, unfortunately (was going out for dinner so couldn't be bothered to wait and threaten them afterwards).
However I still think my original idea (thought when Kidd was manager) was the best. Each week, you put one of the players who are NEVER going to play for us again on the bench (now it's- for example Amoruso, it used to be the likes of Simon Grayson and Egil Ostenstad). You plant baseball bats around the ground. if the ref or linesman is having a mare, the useless sub goes to warm up, grabs the baseball bat when the lino/ref comes near and decks them- ensuring that they won't be able to continue.
They get banned (not a problem- they're never going to play again) and we get a different ref/lino who MIGHT have learned their lesson! It would only take a couple for them to learn to think about their decisions.
