Arsene Wenger is hopeful Arsenal will complete the signing of Valencia defender Shkodran Mustafi.
The Gunners have been heavily linked with a move for the German in recent weeks but as yet have failed to agree a deal, contributing to discontent among supporters with regards to their lack of action in the transfer market.
Wenger insists negotiations are still ongoing but did admit to frustration in his search to identify suitable targets.
"Mustafi? We hope it will be done," the Frenchman told SFR Sport. "We are struggling to find the players we need.
"He is one of a number of players we are looking at. Negotiations are ongoing."
