Arsenal forward, Aubameyang will want to know how much the club will spend on players this summer, Campbell has said.
Campbell recently revealed that contracts are down to trust these days at several top football clubs.
According to him, the Gabonese striker will need assurances from Arsenal regarding their ambition before he would decide to put pen to paper.
He added that the African is looking to challenge for more major silverware before retiring, so the Gunners will have to prove that they can offer him success.
His words, “He’s got to settle down and have a conversation with the manager and he needs to have a clear understanding of what they’re looking to spend, who they’re trying to get in,”
“It’s going to come down to trust, can he trust the club to say, ‘right we are looking for x, y and z, we’re going to bring two or three players in’ and I think they’ll push us on to really challenge for the top four, or really you never know [with] the Premiership.
“He needs to sit down with his people and have a serious conversation about where the club is going in the next two or three years, because he hasn’t got five years, six years to say let’s see how it goes, he needs almost instant success now.”
“Sometimes you need to spend a lot of money, but, sometimes you get really lucky and have a lucky, fantastic year. You’ve got to say Leicester, they just kept on going, it does happen.
“I think he [Mikel Arteta] is trustworthy, there’s no doubt, he [Aubameyang] has to decide himself where he wants to go in his heart and soul and spirit.
“Where does he feel that, ‘If I can do it here I’ll just stay here I’ll give it a go, I believe they’re going to get two or three players in and I’ll believe in them.’
“That’s what it comes down to, no one’s got a crystal ball, it doesn’t matter, you can spend £150-200 million, it doesn’t bring you any trophies.
“It can probably help the profile of the players around you, but not necessarily end up winning something.
“Sometimes you’ve got to trust yourself, your own instinct and hope it matches up with the hierarchy.”
