I sat in the North Stand on Friday for the first time since the cladding was on and I didn't think the cladding had made a jot of difference outside (wind still funnelled through) but the concourse was like another stadium completely. It was dry. And not windy!
I stood in the West Stand for the international, just after it had been clad and the difference in that stand was enormous, both outside and to the concourse.
How anyone could have debated the need for cladding, if only in relation to the safety and comfort of the concourses, I do not know.
