I'm pretty sure (and I could be mistaken), that there was a thread around the time people were complaining, about a team that had a shirt that had their sponsor printed, and the thread was on the lines of "see it can be done". I think it was a German or French lower league team. Perhaps [MENTION=268]Superphil[/MENTION] can shed some light?
Fair enough. Even Juventus have a panel.
Regardless, if we go for a plain coloured shirt, it permits individual letters to be stuck rather than a panel, and that would get rid of about 95% of the complaints.
