I have always thought a Captain in goal is not a good idea when dealing with Refs like Yesterday. The Captain does have "special" allowance to get in the Refs ear and ask for a reason about certain decisions. Lots of teams can be seen doing this and as long as the Captain isn't a dick about it, can be done in such a way not to piss off the Ref, but to also make them very aware of the "one-sided" situation. A Keeper can do this to some degree, but he isn't going to sprint 70 yards out of his goal to ask the question each time - not sure Hugo has that sort of Character anyway.
See Harry doing it occasionally, but really needs the armband to do it with any authority.
