I've explained this 4 or 5 times in this thread
Striped shirts only need to be patched if the Number and lettering being put on the back does not stand out from both of the shirts primary colours
since sunderland will presumably use black lettering they dont need patches but because we use either black or white we DO need a patch
if we used red lettering (which would look fantastic) we wouldnt need a patched shirt
so how will the back bit look like?? have a pic??
