As an avid FM fan I'm finding it very frustrating that all kits remain the same season up on season whilst playing in career mode. I'd like to see new kits introduced pre season for all teams as this is a highly anticipated time of year for fans of any club. This one little change would be amazing and add more realism to this fantastic game.
I would love to see an option to change a teams 1st, 2nd and 3rd strip as well as the keepers strip after every season. Maybe look at offering a choice of strips and letting fans choose which one to pick, or clubs been in a position to negotiate with brands such as Nike, Umbro etc. Just a small idea that would make a huge difference to an already amazing game.
