The Gunners boss believes that, with European clubs still in the market for fresh faces, there are more deals to be done in north London this summer
Unai Emery is expecting more movement at Arsenal before transfer windows across Europe close, with the Gunners open to sanctioning further departures.
The summer at Emirates Stadium has been busier than many expected, with late incomings wrapped up on deadline day.
Kieran Tierney and David Luiz have joined fellow new boys Gabriel Martinelli, Nicolas Pepe and Dani Ceballos in north London, while a deal has also been done for Saint-Etienne defender William Saliba.
