The Reds are currently in a rich vein of form away from home - having won each of their last four games in all competitions, scoring 14 goals in the process - and they come up against a side this weekend which has the joint-worst defensive record in the division.
He said: "You should never take anything for granted but it does appear that Liverpool away from home are looking pretty much unstoppable and I do expect them to simply run away from Newcastle.
"It’s been a happy hunting ground for a number of years and Liverpool are capable of scoring a lot of goals there and I don’t think they’ll have an answer to our running power.
"Although Newcastle spent big in the summer they bought relatively unproven Premier League players who are going to take time to settle.
"They should have gone for some proven Premier League quality. Aleksandar Mitrovic might turn out to be a great striker but I would have paid £2million more to get Charlie Austin who is proven in the Premier League."
Newcastle desperately need to pick up just their third win of the season, but conceding eight goals in their past two games against Leicester City and Crystal Palace should be alarming for the side. The example that Molby has highlighted of their transfer dealings is probably a good one, but they need to be more concerned about things at the back right now.
Steve McClaren will be hoping for some respite from Liverpool, but given their recent form, it is perhaps the wrong time for his men to come up against Jurgen Klopp's side, who are red-hot favourites for this one.
There have been times in recent years when Newcastle have got the better of Liverpool on their own patch, but on other occasions the Reds have managed to dish out a thumping. It will be interesting to see what follows on Sunday afternoon.
