Sadio Mane’s penalty was levelled by Andreas Pereira’s free-kick during the first half of a keenly-fought International Champions Cup encounter.
But Jürgen Klopp’s side raced clear in the second period courtesy of Daniel Sturridge’s careful finish, a Sheyi Ojo spot-kick and a sensational Xherdan Shaqiri overhead kick.
The win provided a perfect conclusion to a successful trip to America for the Reds, who now head back to Merseyside before continuing their preparations at a training camp in France next week.
Any possibility that the match could be a ‘friendly’ was put to bed by a feisty early challenge between James Milner and Pereira.
