Agreed. Since I've been following Boro, we've always had the whip hand. 18 wins to their 10, going back to 1989. If you're of the 70s vintage, our record is even better.
There have been clubs, Ispwich and Watford spring to mind, against whom we've had long losing records by which I've felt a bit scarred, and even when losing streaks are ended, I don't look forward to playing them.
With Sunderland, it's the other way around. Only a fool would deny they've started better than us, but I'll be a little disappointed with anything less than 3 points tomorrow. I feel this every time we play them. Of course, if you play someone enough, every dog has it's day, but that doesn't change my expectation on each occasion we meet.
