Emery has wasted little time in the transfer market, securing moves for Bernd Leno, Sokratis Papastathopoulos and Stephan Lichtsteiner as he looks to make his mark on the squad.
The marquee signing is believed to be the Barcelona and France winger Dembele.
Dembele scored three goals last year for Barcelona and despite his inability to hold down a starting spot, the club remains convinced by the Frenchman's potential, which is making them reluctant to sell.
Barcelona president Josep Bartomeu recently threw water on the idea stating: “Dembele leaving? It’s not on the table. He’s an investment for the future. He’s very young and we expect a lot from him. When a player comes to Barca, it’s because Valverde wants them.”
It seems Emery will definitely look to add a winger before the transfer window closes though, Arsenal have also been linked with Gelson Martins, Cristian Pavon and Lucas Vazquez this summer.
