That this can still happen these days.

I dont know what its like now back in Australia.

Here in switzerland we have a system where you need to fill out the team sheet online via certain system before the game (there are deadlines up to when this needs to be filled out). Ofcourse you have the chance to change the lineup i.e player unable to play and then call someone up. or starting line up changes on the print out.

in the system you are unable to select players for the team sheet that are ineligable for various reasons including (intern club suspension e.g not paying yearly fee) to suspensions from yellow cards etc.

All fairly straightforward and this information is then also used on the Football Federations website for results etc.
