Manchester United registered their first home win of the Premier League season after defeating newly promoted West Bromwich Albion 1-0 on Saturday night.
Alex Telles was handed his first league start in the place of the injured Luke Shaw while there was no place in the squad for Paul Pogba.
The Red Devils should have gone ahead on 16 minutes when Rashford and Mata combined to set up Anthony Martial, who was denied by Sam Johnstone from close range.
West Brom went close at the other end as Romaine Sawyers played Karlan Grant on the right side of the box, but the latter's effort forced David De Gea into a finger-tip save.
While United continued to dominate possession for most of the half, the visitors nearly snatched the opener before the break as Bartley's looping header sail onto the roof of the net.
West Brom were awarded a penalty shortly after the break when Bruno Fernandes appeared to foul Gallager, although the referee reversed his decision after a review on the Video Assistant Referee monitor.
In a funny turn of events, United were awarded a penalty in the 53rd minute when Mata's free-kick struck the arm of Furlong. Fernandes saw his spot-kick saved by Johnstone but a re-take was ordered after the goalkeeper moved off his line, which allowed the Portuguese star to convert on the second take.
West Brom came agonisingly close to pulling level after the hour mark as Callum Robinson rattled the crossbar with a powerful strike from the edge of the box.
Chances began to fall an alarming rate for United at the other end, but Rashford somehow failed to find the back of the from six-yards out after being picked out by Fernandes.
In the end, Fernandes' goal was enough to seal three points for the Red Devils who moved up to ninth spot.
