Pierre-Emerick Aubameyang would be a good signing for Barcelona.
That is the view of Brazil legend and former Barca star Rivaldo.
The 30-year-old's contract at the Emirates Stadium expires at the end of the next season and rumours persist regarding a possible departure in the summer transfer window.
Links to Barcelona as well as Real Madrid and Manchester United refuse to go away and Rivaldo has had his say on a potential move to the Camp Nou for the Gunners captain.
"Barcelona always looks for the best players available in the market and Aubameyang is obviously a great player who could be a boost for the club," Rivaldo told Betfair.
"But other than simply signing a player, Barcelona must study if a certain player will fit into their current system, or if a transfer could end up forcing the new player to play in a different role, harming his own performance and potentially causing the team problems as well.
"So, it's crucial to analyse these factors carefully before making an offer to sign a player, as it isn't just the taste of the president and board that should decide this kind of stuff.
"You need to understand if the manager would approve of it and will have a space for the player in his system.
"To fit on a new team's system is crucial, so Barcelona must be aware of that all the time and ask: Would that player fit on Quique Setien's system?"
Should Arsenal sell Aubameyang then they would certainly need a replacement.
And Rivaldo might have the answer with Ousmane Dembele as the Brazilian is backing the Frenchman to fulfill his potential elsewhere after struggling at the Camp Nou following his
"Ousmane Dembélé signed for Barcelona almost three years ago and he has already had enough time to establish himself in the club and prove his value," Rivaldo added. "It's possible that he will never show his quality at the club.
"He is still a player with huge potential, but I think this summer could be the right opportunity for Barcelona to sell or even exchange him for a player they're chasing already.
"He's been unlucky with injuries, but he might also have tried to give more at some moments. Things haven't gone according to expectations and he might be able to revive his career at another club where he will feel more confident to play at his best.
"Barcelona seems to be trying to sign Neymar and Lautaro Martínez, so Dembélé will probably struggle to get in the first team next season. Additionally, Barcelona would need to reduce its squad and earn some money if they really want to succeed in bringing in their current targets. To sign new players, others must leave."
