Mason Greenwood scored his first senior goal as Manchester United comfortably beat Leeds United 4-0 in Perth.
The teenager struck home after just seven minutes before Marcus Rashford added a second midway through the first half.
Defender Phil Jones, on as a substitute, headed home from Andreas Pereira's corner for United's third and Anthony Martial added a fourth from the penalty spot as Ole Gunnar Solskjaer's men ran riot Down Under.
Having named a fairly strong line-up, with Juan Mata captaining the side, Solskjaer would have been expecting a decent performance with the Premier League season only four weeks away.
Injuries to Romelu Lukaku and David De Gea may have disrupted Solskjaer's preparations but the Norwegian would have been impressed with the intensity his side played with from the first minute.
It was Marcus Rashford who had the first chance to open the scoring, striking a low effort against the post after a surging run from Victor Lindelof.
But United got in front just a few minutes later when Paul Pogba slid in Aaron Wan-Bissaka and the full-back sent a low cross into the box, which Greenwood tucked away superbly.
Rashford would eventually got on the scoresheet after 26 minutes, jinxing past two defenders before smartly finishing beyond Kiko Casilla. That was his second goal in as many games after scoring in the 2-0 win over Perth Glory.
After making 11 changes at half-time, Solskjaer might have expected a drop in intensity. But United were three up shortly after the interval, with Phil Jones meeting Andreas Pereira's corner with a bullet header.
Tahith Chong, playing in a free role in midfield, was looking promising and it was the 18-year-old who played a major part in the fourth goal.
The youngster played a fine one-two with Angel Gomes before being brought down by Liam Cooper. Anthony Martial stepped up and sent Casilla the wrong way to wrap up a very encouraging pre-season performance from the Red Devils.
