Kai Havertz skied an attempt from close range in Arsenal's FA Cup third round clash with Manchester United on Sunday.
After a tepid first half, the game exploded into life after the interval with Bruno Fernandes giving his side the lead at the Emirates.
Shortly after United were reduced to ten men when Diogo Dalot was shown a second yellow card for a mistimed challenge on Mikel Merino.
Mikel Arteta's side quickly utilised their advantage and Gabriel put the Gunners back on level terms with a deflected volley.
