Arsenal manager Arsene Wenger has identified Shkodran Mustafi as primary target to strengthen the defensive department.
The Germany international will be in England next week for Valencia's friendly game against Crystal Palace with reports in Italy claiming that he will take advantage of this trip to finalise his move to the Emirates.
The 24-year-old will take over from Per Mertesacker who will spend the next months on the sidelines after suffering a knee injury during the pre-season friendly against Lens.
Sky Sports has already published an article explaining how the central defender will fit in Arsene Wenger's line-up.
The Gunners are still in the market to sign a new striker.
Having failed to secure the services of Jamie Vardy, Alvaro Morata, Gonzalo Higuain and Alexandre Lacazette, manager Arsene Wenger has turned his attention to Internazionale's Mauro Icardi.
But the Argentinean is also a target for Napoli who are in pole position to sign him.
