How does captaincy affect your player and team?

[bridgy]

In my experience with 5 teams, there is one definite effect of captaincy: if you sell a player on your captain list (even if he is 4th or 5th down the list) your team gets terrible form. And removing him from the list just before selling doesn't help. My hunch is he needs to be off captain list for 1 or 2 competitive games but I don't want to test this too much since it means I sell all my good players and have terrible form...

No I don't have *hard* evidence but it always seemed to happen to my teams over the last 10 seasons.
