What’s the difference, they didn’t for the semi finals either as far as I’m aware. They don’t check anyway, scan barcode, put in pocket and walk through.
The FA cup and league cup tickets have always been different from each other, it is not wembley but the competition owner who gets them done, and they use different systems for concs.
They did write on for the semis for some at least, and it would come off if someone was paranoid, but I know they don't check, and there is no lighting system or anyway ways of knowing from a back end database flagging them. Contrary to what Stretford Blue said, there is no system like city and it would be impossible as they are all printed off well before they are sold and the category is not known then.
