In simple terms, we conceded far too many shots from dangerous positions and got away with it, though unlike Mourinho's 2nd season, it wasn't due to De Gea making incredible saves, as both his save percentage and his post shot expected goals minus goals allowed stats are fairly average for PL keepers this season (United rank 8th for both according to Fbref)
