As for the keeper thing, I can hardly think of one occasion in around 10 years of following Town where a sub keeper has been needed
So in conclusion then a keeper on the bench might not be such a bad idea...??
OK my memory has let me down...
But even so if it happens once a season, that is once in (probably) over 50 games!
Think of how many times you could be restricting your outfield options just to have that safety net
