You can get a 'bespoke' design, but you have to guarantee a minimum order, and most clubs simply don't have the cash flow, or back up funds, to guarantee selling that amount of shirts. We're small fish unfortunately.
I love the jersey. It's a shame both clubs boards looked at the options and picked the same one, but I guess both thought it was the nicest! Slightly different shades of green but not really noticeable.
Don't see it mattering a huge amount, but odd nonetheless.
