Antony debut goal and Rashford double see Man Utd end Arsenal's perfect start
Antony was making his first appearance after signing from United manager Erik ten Hag's former club Ajax in an £82 million ($94 million) deal on Thursday.
The 22-year-old forward took just 35 minutes to get on the scoresheet in a dazzling introduction to his new fans at Old Trafford.
Arsenal hit back to equalise through Bukayo Saka, but Rashford blew the leaders away with two goals in the space of nine minutes.
Thanks to Antony and Rashford, United recorded a fourth successive victory that lifted them to fifth place.
Arsenal's first defeat this term after five successive wins was cruel on Mikel Arteta's side, who played well for much of the game but paid the price for some naive defending.
The Gunners thought they had snatched the lead in the 12th minute as Gabriel Martinelli raced away from Diogo Dalot to clip a fine finish over David de Gea.
But VAR intervened to ask Paul Tierney to check for a foul in the build up and the referee ruled Martin Odegaard pushed Christian Eriksen to steal possession.
- Audacious Antony -
Antony put United ahead in the 35th minute when Rashford's pass reached the forward, who placed his shot into the far corner.
Confidence clearly was not a problem for the Brazilian, and he tried an audacious lob that kept Arsenal keeper Aaron Ramsdale on his toes, before he departed to a standing ovation after 58 minutes to be replaced by Cristiano Ronaldo.
Saka silenced Old Trafford two minutes later as Arsenal grabbed a deserved equaliser.
Odegaard's pass unhinged the United defence and when Dalot's tackle on Gabriel Jesus diverted the ball to Saka, the England winger slotted home.
The leveller didn't last long, as United caught Arsenal with a brilliant counter in the 66th minute.
Playing through the visitors' press, Eriksen found Bruno Fernandes and his superb pass sent Rashford clear to fire past Ramsdale.
United wrapped up the points with a replica of their second goal as Arsenal once again left themselves open at the back as Eriksen fed Rashford to slot home.
