I saw Ken's list earlier in the season and worked out then I'd then I'd been at ten of the games against teams we'd only played the once. I know this won't be the highest, indeed I don't think I even beat the one person I asked...
And P86, I think Ken's list is competitive games only, as for instance we played Rotherham in the cup in the early 80s and in a pre-season friendly a few years back and yet they're down as a team we've played just the once.
