WATCH: Romelu Lukaku scores first Manchester United goal in 2-1 win over Real Salt Lake

Romelu Lukaku netted his first Manchester United goal in a win against Real Salt Lake that came at a cost, with Juan Mata injured and Antonio Valencia sent off.

Two days on from a comprehensive friendly victory at the LA Galaxy, Jose Mourinho's men made the two-hour flight from their California base to take on Utah's Major League Soccer side.

This was a harder workout as United could only earn a 2-1 success, with Lukaku finding the net for the first time since his big-money move on a night when Mata was forced off and Valencia sent off.

Luis Silva gave Real Salt Lake a deserved lead that was swiftly cancelled out by Henrikh Mkhitaryan, before Lukaku scored his first United goal.

It proved the winner after a second half that had needle if not chances.

Mata went off with ankle complaint sustained in a challenge by Sebastian Saucedo, who was latest forced off himself after a Valencia tackle that saw the right-back handed a red card after referee Allen Chapman spoke to Mourinho.
