If they'd have released this information with sketches and renderings, my guess is we'd all see there's nothing to be concerned about.
They didn't, so naturally the sky is falling.
There are two factors that in tandem that tell me we don't need to worry.
Firstly, everyone who's seen the plans and spoken on this says that this won't affect the intimate, intimidating atmosphere we're looking to capture. Even the architect says this, for crying out loud.
Secondly, the fact that Anfield is to be used for the Opening Ceremony tells me that the capacity of our ground in athletics mode will be drastically reduced.
That's a good thing.
It suggests that the running track has to be much higher than the pitch - perhaps a full tier higher - which would therefore indicate that the stands are as steep as we've been promised.
