The old air on the pitch thing
I think it's all rubbish about "air to the pitch" being the reason the stadium is left wide open. The pitch is outside, it's a open roof stadium so I'd say it's pretty much getting air to it.
My lawn grows pretty well in my back garden and it's got big 6ft 6in fence all the way around.
