I've got a request.
I'm trying to create a FM version of the inter-cities fairs cup, an old competition (forerunner of the modern Europa League) in which every city was represented by a single team, combining the main city's clubs.
For every XI team, I'm trying to do a "mash-up" kit that combines, in fair measure, the colours of the participating teams. While it is relatively simple to do a mash-up kit of a city with two single-coloured clubs, I found it hard to create a kit for London (because of the great number of teams in the top leagues) and Genoa (because Sampdoria's horizontally-striped kit is difficult to combine with vertically-split Genoa FC kit). Who can help me?
