I dont understand peoples problem with the NSK, they arent doing anything wrong but people seem to think that they're acting as superior fans which isnt the case, as they first said 'this is a new era at the club' and they wanted to bring something new.
fans are entitled to leave early, IMO they showed their support by turning up and supporting the team. Those who leave early may not feel the last few minutes is important to them and would rather get home quickly, fair play to them, it isnt a crime
