That comes from United fan and talkSPORT host Andy Goldstein – who has claimed to have received a major tip-off.
United are in desperate need of a squad overhaul with several stars mooted for departure.
Among them include striker Romelu Lukaku, who has frequently flirted with a move to Serie A over the past 12 months.
The Belgian has also lost a guaranteed starting spot after the arrival of Ole Gunnar Solskjaer, who prefers the more pacy services of Marcus Rashford as his main No. 9.
Inter Milan have emerged as the frontrunners for the former Everton forward, with Antonio Conte a known fan after trying to lure him to Chelsea during his time at Stamford Bridge.
Any transfer would likely involve a hefty transfer fee – while United have already reportedly identified the man to replace the 26-year-old.
Aubameyang, who finished as one of three Golden Boot winners in the Premier League, is being eyed up by the Red Devils, according to talkSPORT host Goldstein.
“I’ve got someone on the inside, not at United by the way, someone on the inside who every so often would tell me transfer gossip,” Goldstein said on Monday night.
“I would say he has a hit-ratio of about, quite high, 75-25. He’s told me quite a few that have happened. Not just at United but other clubs as well.
“He told me about Anthony Martial, which I tweeted I think two days before United even approached. It was one of them ‘how do you know?’, one of those.
“He has told me that United are interested in Aubameyang.
“He’s got two years left on his deal, he is 29 years old, he is the finished article. United did something similar with [Robin] van Persie, Romelu Lukaku isn’t doing it for Solskjaer, I’m led to believe.
“Do you want to know the number I’m being told? How much?
“I think it’s crazy money for a 29-year-old, two years left on his deal, scores goals, finished article.
“[£70m] is what I’m being told. There’s a first offer. He’s only got two years left and in a year’s time he can go.
“If you’re at Arsenal and you’re in roughly the same sort of place as United at the moment and United come in for you, where would you go?
“I think he fits quite well [at United].
“I’m not saying it’s going to happen but the person who told me as I said is a 75-25.”
