Manchester United weathered a storm to secure a 2-1 victory on Saturday that leaves Arsenal 15 points adrift of the Premier League pace.
The hosts dominated for most of the opening hour at Emirates Stadium but found United goalkeeper David de Gea in excellent form.
The same could not be said for De Gea’s Arsenal counterpart, Wojciech Szczesny, whose failure to deal with a ball into the box led directly to Kieran Gibbs’ 56th-minute own goal on the end of Antonio Valencia’s drilled cross.
United then made light of high-profile defensive absentees by closing out their first competitive away win of the Louis van Gaal era, a triumph sealed by Wayne Rooney on the counter-attack five minutes from time.
It could have been three late on when Angel di Maria missed with a one-on-one breakaway opportunity, before Olivier Giroud gave Arsenal something to cheer with a superb finish on his return to the side after a fractured tibia.
There were, though, injuries to Jack Wilshere and Szczesny as Arsenal’s miserable record against United was extended to only one win in 15 attempts – and the gap to Premier League leaders Chelsea was extended even further.
Danny Welbeck shook off a hamstring problem to lead the Arsenal attack against his former club, while Arsene Wenger preferred Mikel Arteta to Mathieu Flamini in midfield.
Van Gaal’s latest response to United’s defensive injury crisis was to name Tyler Blackett and Paddy McNair in a re-shaped back three.
McNair produced an important early block to deny Welbeck and the England international headed over in the ninth minute as Arsenal began in the ascendancy.
