A second-half penalty from captain Pierre-Emerick Aubameyang gave us a richly-deserved three points at Old Trafford - our first Premier League win there for 14 years.
We were the more positive side right from the opening exchanges, snapping into tackles and closing down well, and much of the opening quarter of an hour was played in the United half.
Our first sight of goal came when the overlapping Hector Bellerin fizzed a low ball across goal, but it was just ahead of the sliding Pierre-Emerick Aubameyang at the far post.
Despite our superiority in terms of possession, it was United who had the first shot on target when Mason Greenwood ghosted in at the far post to draw a smart low save from Bernd Leno.
