The Gabonese marksman has netted a staggering 49 goals in 77 games for the Gunners since joining from Borussia Dortmund in January 2018.
And according to The Athletic, Arsenal were not the only club who had their eyes on the striker.
The report states the Red Devils scouted Aubameyang between 2016 and 2017, where he bagged 73 times in 91 games for the Bundesliga side.
It is believed Old Trafford chiefs were not convinced the forward could cut it in the Premier League, and also had concerns over his hefty £70m price tag given he was 30 at the time.
