The famous red and black strip which we wore when we won 3 major trophies (out of 8 at the time) ... wasn't that our designated "cup strip" for a time? There was certainly talk about giving it that status.
Memories fade but I seem to remember us playing in it at least once, at Maine Road, in a cup tie, when I was a kid. Can anybody clarify if I'm right or not? I'd be obliged as its starting to bug me!
I've no problem with red and black (actually it was black and red) or maroon as our away strip, in fact given our history of success wearing both (1956 Cup Final was maroon) then I'm in favour. I think maroon also relates to one of our predecessor clubs in Gorton so there's loads of club 'istory to both.
Home strips for me though should always be blue. Anything else, especially red, wouldn't feel right.
