Actually, I think it does matter. I have had my assistant tell me that the players were finding it hard to get motivated to play with Edin Dzeko as their captain. He is probably the best player at my club, but his influence is not very good (around 10 i think). However this only seems to happen if he is going through a rough patch of form. I made Modric, who has very high influence, my captain for the next season and I never had this happen regardless of his form, so I think influence does play a role.

I don't know whether that's true as I had my assistant telling me that the players were struggling to get motivated with John Terry as their captain when he has influence of 20 (or 19 I forget)
Check personality , getting a player with influence 20 and " Ambitious " as a trait might backfire , try always to get 12 +++ influence with a professional or determined player
