Napoli defender Kalidou Koulibaly could be Unai Emery's first signing according to Express Sport.
With Laurent Koscielny set to miss the start of the new campaign, the Gunners are in desperate need of a new defender.
And the 26-year-old is one of the many players followed by the club.
Meanwhile, agent Bruno Satin has confirmed that his client has attracted the interest of a number of "big clubs".
"It is obvious that he is interested in the big clubs, like all the important players of Napoli, he has a contract with the club, he cannot run away," the agent is quoted as saying by Tribal Football.
"Now he has closed the season, unfortunately he has had the disappointment not to win the championship, but he is lucky to have the chance to go to the World Cup, he is about to leave with Senegal and it is another goal of his season.
"If he is happy at Napoli? Absolutely yes."
