James Milner’s deflected shot and penalty gave the Reds an early two-goal lead before Rhian Brewster added a third before the half-time break.
There were no further additions to the scoresheet in the second period for Jürgen Klopp’s side, though Bradford did pull one back from the penalty spot through Eoin Doyle late on.
Nevertheless, Liverpool picked up a second victory in four days prior to jetting off to the United States on Tuesday.
The fixture was, of course, not only about the teams’ preparations for 2019-20. The match was also scheduled to raise funds and awareness for the Darby Rimmer MND Foundation – the charity organisation that was set up after former Reds and Bantams defender Stephen Darby was forced to retire from professional football last year at the age of 29 having been diagnosed with motor neurone disease.
