Former Arsenal captain Robin Van Persie believes the club must promise top signings to Pierre-Emerick Aubameyang.
The Gabon star has less than a year left on his contract, and the club might have to sell him if he does not extend before the end of the transfer window.
And Van Persie believes it is not only a matter of money, but showing Auba that the club has the ambition to sign top players and compete for league titles.
He told Stats Perform News: "Arsenal would like for him to stay, he hasn't really come out yet with his opinion. He got asked the question after the FA Cup final and he didn't answer so I don't know.
"I don't know what he thinks, I don't know what Arsenal have offered him and I'm not really talking about money, I'm more talking about players because players like him want to play with world-class players. He is a world-class player in my opinion, and he wants to be surrounded by world-class players.
"Then you have to ask him, and it's up to him, if he thinks that he can win the Premier League at Arsenal. Because winning the FA Cup was very nice but these types of players, and Arsenal Football Club, want to compete for the Premier League and the Champions League. That is the big goal. You want to compete with the best teams that there are.
"I can't really judge from the outside but you have to just put it in place. Arsenal need to make their mind up and Aubameyang as well and find each other or not.
"That's how it is and in the end, part of it now is business and he will calculate that for himself and the club will do as well."
