Probably a fan of a rival club on a wind up, there has been some more money placed on it being Williams though as his odd's have dropped today from 4/1 back to 11/10 (Buckingham is 4/6) but realistically it means nothing as they have no clue who it actually is, odd's are driven purely based on punters bets placed.
I'm quietly confident that we'll be celebrating 3 points chanting Luke Williams black and white army come Saturday afternoon.
