Romelu Lukaku scored his first Manchester United goal as Jose Mourinho's side overcame Real Salt Lake 2-1 in a fiery friendly in Utah.
The Belgian, 24, who signed from Everton for £75m, got the winner seven minutes before half-time to add to Henrikh Mkhitaryan's equaliser after United had fallen behind on 20 minutes.
United then lost Juan Mata to injury and Antonio Valencia to a red card.
"[Lukaku's goal] is nice for him but not important for me," said Mourinho.
"I told him I love what he does. He assists, he moves. He holds the ball well. I like everything he does."
Mata limped off following a heavy challenge from Sebastian Saucedo but is expected to be out of action for a week at most.
Valencia was then sent off for a tackle on Saucedo, referee Allen Chapman speaking to Mourinho before belatedly dismissing the Ecuadorian.
"The delay was because the referee asked me to change the players and I didn't because I don't agree with the card," added the Old Trafford boss.
"Saucedo was really aggressive with what happened to Mata and some other actions where he was a bit dangerous. It's pre-season so no problem - it's a good experience."
United face Manchester City in Houston on Friday morning UK time (02:30 BST).
