Mate you can copy and paste all you want I'm just passing on info and I'm not really bothered why we have a 3rd kit anyway. Find a source regarding kit regs and let us know.
I'm only telling you what I've been told by the guy at UA
Perhaps regulations have changed regarding Europe and in European comps a third kit is needed and it's easier to get everyone to have one now incase of future qualification. I don't have UEFA contacts just kit ones.
Old man Steptoe has told me a Red /White home with a sort of stripe, take that whatever way you want with a plain red back.
Blue and Yellow away and that hideous light red dark red is 3rd kit as per regulations regarding Europe.
