Doesn't matter, I'd bring sandwiches.
I know what you're saying, I really do. No matter what happens though, I'll be supporting the yellows.
Like you, I used to work for a [relatively] small [Oxfordshire] company that were taken over by a bigger investor. In fact, they became a billion dollar company during the dot com bubble and made me redundant when the bubble burst.
However, I still follow that company and love them and the same is true of OUFC wherever they end up. Hopefully, a top 30 club as suggested by the current owners!
