Martin Odegaard had immediately cancelled out Marcus Rashford’s opener in the first-half, and the game appeared to be heading towards a stalemate after Alejandro Garnacho saw his 88th-minute goal rightly chalked off for offside.
However, Declan Rice scored in the 95th minute to send the Arsenal supporters into ecstatic celebrations, and Man United attempted to salvage a draw by going all out in attack after play resumed.
It proved costly as the Gunners caught them out on a counterattack, with Jesus beautifully flooring Diogo Dalot with a sublime piece of skill before putting the ball past Andre Onana.
The Brazil international striker took to Instagram to celebrate the win, and his international teammate and Real Madrid Vinicius Junior was pleased with his performance against the Red Devils, taking to the comments section to react in three words.
Jesus was making his second appearance of the season having missed the games against Nottingham Forest and Crystal Palace due to an injury.
He spent just a few minutes on the pitch in the 2-2 draw against Fulham having been brought on in added time, and h was given 15 minutes to prove his quality against Man United.
The former Manchester City star did not disappoint, and he could be getting his first start of the campaign when Arsenal travel to face Everton at Goodison Park on September 17.
The striker was excluded from the Brazil national team squad for the 2026 FIFA World Cup qualification matches against Bolivia and Peru this month so as to continue his recovery, and he will be much sharper and expected to hit the ground running when Premier League action resumes.
