Fairy 'nuff. I was there in the late 60s - early 70s, and never heard it. Times change though, so maybe 'wools' has become part of the vernacular since.
Scousers can't come back with a witty put down when they need to? Where have you been living the past (insert number of years you've been alive) years?
To be fair, to a neutral looking at 11th at home to 13th, with 13th having a very poor away record, a 2-0 home win isn't an unlikely prediction. To us, of course, who are biased, it's very different!
