They were getting 10k plus in the national league with most games completely sold out.
Obviously before the hype they weren't doing that but don't underestimate the power of Disney etc......
It's amusing to see people talk about the size of the town as if that's the main metric. They've become and are becoming more of a reality TV football side. They are aware of it and embracing it. The attendances go up everywhere they go.
They'd easily sell out 30k Week in week out in the Premier league.
