Its also the run up to Xmas remember, Utd have shirts to sell.
I recall few years back Celtic registered their new kits with the powers that be, the goalkeeper choices were black, or yellow. (bear in mind you wont see much blue on a Celtic shirt). The referee colours that season (and the clubs had been informed of such before the launch), were, black, yellow or blue. Should someone have been strong enough to say, sorry Celtic, you will need to have a 3rd or a change your 2 keeper jerseys? Even before you think of the ref now being forced to wear blue, you then have Celtic v St Johnston, Rangers,etc. Its the LOTG yes but nothing in life is perfect.
