Just received the Umbro football kit brochure for next season through the post.
Could be a couple of clues in there.
A new sash kit with a collar called 'Vasco' is shown. Picture in the brochure is of a white shirt with red (vermillion) sash. Design also available in other colours.
Another range called 'Winchester' is also shown. This range has picture of a yellow shirt with blue neck and cuffs and a thin blue stripe vertically on the outside of front on each side.
