I don't agree. The Etihad can go well beyond that and look at the setting and compare it to our ground. No comparison.Giant single goal end tier, with a low roof, and they even have some kind of contraption hanging from the roof to further keep the noise in and direct it out towards the pitch.
Really jealous, to be honest. Looks absolutely quality.
Money is no object for us, so it's a shame we didn't really push the boat out and do something similar. But I suppose it's easier to build it from scratch like Spurs are doing.
