No, but just putting some context to the figures. The 9 in a row wasn't what caused the big problems for Murray, it was the Advocaat era and chasing his Champions League moonbeams when he started introducing the EBT's and spending £12M on the likes of Flo.
Actually talking about dominance, unless 1 of the clubs is having a disaster in the boardroom of epic proportions, I don't think 1 club dominates over the other for any great lengths. 1 club wins a couple, the other club regroup, comes back & wins 1 or 2 etc. I think to 1 club to really dominate the other club has to go or almost go out of business.
