I find it impossible to change roles!! i cant drag anyone and replace their roles.. I want to change captain and kickers but it wont let me! Is there some unique way u have to do it?

Thanks alot guys

i dont understand....when you go to the roles screen the only thing you have to do is to put the player you want at the top the list, for example: you want Del Piero as Captain, you push over Captain and move Del Piero at the top of the list in the right part of the screen, you say you cant do this????, remember if you change the roles in the middle of a match, for the next match the roles will not remain, you have to change the roles in the week or before a match
