Just watched the video of last nights coach arrival and one Everton staff member gets hit on the head and face and is led away for treatment. To those who bring flares and fireworks to games well done, you could well have nearly blinded someone.
I would think the drainage was the first thing installed, as for cost it doesn't matter how much is spent, at the moment we have an expensive colander.
When the new St Helens stadium was built they were going to use cladding with holes in it like Everton have used. They soon realised it would rain in and installed solid cladding. When I first saw the cladding on the new Everton stadium I wondered if it would be watertight.
