In all our years of dominance, Liverpool turned out some pretty ordinary sides with the Djimi Traores, Bruno Cheyrous, and Sean Dundees, but I can't remember many travesty-like performances among SAF's thirty wins. I mean, I think he only ended up with a marginal positive goal difference across all the games.
So, despite United generally being favourites every time they faced Liverpool, they were still made to work hard for the points even while Liverpool hadn't won the league since before the Prem had started. In fact, Liverpool would nearly always put up ferocious performances at Anfield and go to Old Trafford with something like a plan that United would have to break down.
By contrast, how many genuine drubbings have United suffered since Liverpool first won the league? It's almost becoming routine now to lose this fixture by being steamrollered.
It just indicates how gutless the players are.
