The black shirt will sell very well, the home shirt will sell less than the last one would be my guess but we're never going to know for sure, there's no value in the club releasing sales comparisons. I'll be getting my Skalak 8 away shirt at some point this month.
Isn't it nice that we're having the same postings from 2008/09 when we last had the "two kits" comments. "One for attacking, one for defending". Literally quoting 8 years ago.
