You'd think were the only team in the country who has fans that moan/criticise/complain at the drop of a hat. this happens with ALL teams, it's not just us.
This happens in football, it won't change either. The players will receive overwhelming praise at times and others they will be treated like a persons worst enemy, this is the same for all clubs. It's not ideal but it's just the way it is, I imagine everyone posting has called/slagged off a player in their day.
Edit: The above sounds like I'm supporting booing, I'm not, I'm just stating how it is in football in general
