Interesting. I’d never really thought about it before.Here's a little known fact: The "Main Stand", where the directors box and wealthiest fans go, at most old football grounds was always put on the west. It was the case at Maine Road and is the case at The Etihad. There are two reasons for this: The prevailing wind in the UK comes from the west so would be at your back and you'd be sheltered. Also, the sun in the UK is always in the western sky so you'd always be sheltered from that too.
