The Gabon international has just netted 22 goals in the Premier League to finish as joint top goalscorer alongside Sadio Mane and Mohamed Salah, meaning that the Gunners are currently against parting ways with the attacker.
However, a combination of Aubameyang being 30 years of age, having just two years left on his contract and Arsenal's limited transfer budget means that a big-money sale this summer is not out of the question.
Aubameyang and Lukaku are two different types of striker, though, and Ole Gunnar Solskjaer may have to reconsider the makeup of his starting lineup ahead of the top-flight opener with Chelsea on August 11.
Here, Sports Mole predicts how Aubameyang could fit into the team should he make the switch from the Emirates Stadium to Old Trafford.
United already have two versatile forwards in Marcus Rashford and Anthony Martial, and the addition of Aubameyang would leave Solskjaer with opportunities to tinker with the makeup of his front three.
Aubameyang has spent time down the middle and on the left for Arsenal, although he could begin on the right-hand side to accommodate the preferences of his potential strike-partners.
Depending on which strategy is used by the Norwegian, Paul Pogba - should he stay at the North-West giants - will be used in a midfield three or in a more advanced role to support the attack.
Aubameyang would no doubt add to United's threat in the final third, but Solskjaer would have to strike a balance and avoid becoming too gung-ho in search of playing attractive football and scoring goals.body check tags ::
