Pierre Emerick Aubameyang’s second-half penalty handed a win to Gunners at Old Trafford for the first time since 2006.
Mikel Arteta’s men secured an impressive win in a robust performance against the Red Devils. Arsenal started the game brightly as Aubameyang came close to putting Hector Bellerin’s cross in the goal at the 13th minute.
United’s only real chance came at the 20th minute when a delicious ball from Marcus Rashford reached Mason Greenwood whose shot was comfortably saved my Arsenal’s, Bernd Leno.
The Gunners continued to knock on United’s door as Willian hit the post after a wonderful one-two from Aubameyang inside the United’s 12-yard-box.
Arsenal missed another chance just before the half time whistle when Bukayo Saka’s header was just over De Gea’s goalpost.
But United were more clinical in their passing and pressing in the second half. Wan Bissaka and Maguire had great chances before Paul Pogba gave away a sluggish penalty to the North London side after tripping Arsenal’s right-back Hector Bellerin.
Aubameyang coolly scored in what was a first away win for the Gunners against the so-called ‘Big Six’ since 2015. United did hit the post through a deflected shot from substitute Donny van de Beek late in the game but Solskjaer’s 100th game as manager ended in a defeat which leaves them in 15th place with just seven points from six games.
Arsenal have currently the best defensive record in the Premier League, despite already playing Liverpool, Manchester City and Manchester United away.
