Despite slow starts in either half, the Blues romped to victory.
Christian Pulisic scored first two goals for the Blues with some outstanding composure.
The first with a cool finish into the bottom left-hand corner, and the second - an outstanding ball from Ross Barkley. It found the American who ran in on goal and found the back of the net.
Barkley also had his hand in a few goals. He fired in from the penalty spot, making it three in three for the inform midfielder.
He also teed up Pedro with one of the best goals you’ll see this pre-season. He clipped it into the box and a delicious flick from Pedro found the back of the net.
The hosts did get on the scoresheet midway through the second-half to make it 3-1 as poor defending from the set piece saw RB Salzburg take advantage.
Minamino did make it 4-2 with five minutes to go from the spot after Davide Zappacosta gave away the penalty.
Michy Batshuayi then added a fifth for Chelsea late on as he rifled his effort into the top of the net after his initial attempt was saved.
Minamino then got his second of the game in the last piece of action after his initial effort was blocked by Kepa, but it ricocheted back to him and he fumbled it in.
Just one game left for Chelsea as they head to Germany on Saturday to face Borussia Monchengladbach.
Frank Lampard will be extremely pleased with the performances of many, but still, there is plenty to improve on.
