Think the plan is to completely renovate the inside of the Cheadle End (suites and concourse).
It's the first place I'd start, because in normal times, it's the conferencing and banquetting that generates revenue every day of the year. It was a real mess and had become embarrassing, no place to bring corporate clients.
I think the previous owners replaced two blocks of seats in the Railway End, but I think it's important to prioritise replacing the rest - to allow more room for social distancing.
