You get the chance after a dodgy decision to complain.
its not worth it though, nothing happens really if you complain (morale rises) and your right and if your wrong you risk a ban, fine and upsetting the board
There have been a couple of occasions when I'm sure my wrong complaint has got one of my players sent off in a following fixture and when I've been right that I've got a dubious penalty which had the opposition getting booked left, right and centre for moaning about.
It's for sure that complaining has no effect like this?
