The only logo on the front of a shirt I can think of that doesn't make the club look like hoors is Barca's.
Paying money to buy a shirt in support of your team makes sense - you do know you can get the shirts free of the scabby carling logo, yes?
Yeah I always buy my beloved Rangers shirt but since it's had Carling splashed across the chest I've bought it without the Sponsor, however I do feel sorry for the 11 lads that need to put it on every match day. I miss the old CRSMITH and McEwan's Lager days when the shirt was nothing but the beautiful colours of red white and blue.
