With big squads I like to sort my players with the numbers, goalies 1-10, defenders 11-20, midfielders 21-30, forwards 31-40. Similar setup in hockey. This makes it easier when seting up tactics and replacing players that was sent to camp or got injured or sold. Problem with this is that it is messy to remember what number a certain player has, which makes it less fun to watch the games.
I suggest that managers should be able to choose if a player is GK, def, mid or forw. Then there could be a dot with a certain colour for each position, and also to be able to choose that the players will be shown in the order of GK-def-mid-forw. Then I could have for example nr 7 for the player I think should be nr 7, and 9 for 9 and so on. For me it would be more fun. What do you think?
