It's a conundrum. Imo the team look far more nervous at home than away. It might be because there has sadly been very little to cheer at home and the place has been quite toxic on several occasions since we moved there. I also think it demonstrates the obvious flaw in having a huge capacity: you need loads of people joining in to make an atmosphere. WHL was rocking even with half the stadium, which was circa 15k people. The new stadium needs twice that number. From when I've been there the south stand can't manage it on its own, atmosphere gets lost by the time it gets across to the north stand.
The problem IMHO is there are so many fans who stop making a noise when the going gets tough. That was true at WHL too. Since moving into the new stadium we've reached two European finals and won one of them. That's plenty to cheer.
