The club missed out on yet another reported target on Friday, with midfielder Luiz Gustavo swapping Bayern Munich for fellow German side Wolfsburg, meaning 20-year-old Yaya Sanogo remains the Gunners' only summer addition.
The 63-year-old has once again admitted the Emirates Stadium outfit must add to their ranks with quality players, but refused to speak about details relating to specific targets.

When questioned on Rooney he then replied: "I can just repeat the same sentence. We look for quality.
"Usually in the press you are well informed. I don't disagree that we are a bit light at the moment. We are looking to strengthen our squad.
"We're looking more for quality than for numbers. We would like two or three players, if possible more.
"[But] it's not a question of spending money, it's a question of buying the right players."
Wenger was more concerned about the club's injury issues ahead of Saturday's clash with Aston Villa, with a number of first-team players likely to be missing from the matchday squad.
"Vermaelen is out. Monreal is out. Arteta will be out," the Frenchman continued. "Monreal will return soon – the others are a bit longer."
When quizzed on Arteta's likely return, following reports that he could miss more than a month, Wenger admitted: "I don't know."
The Gunners take on Paul Lambert's men on Saturday afternoon, and Wenger is wary of the threat posed by Christian Benteke, who scored 19 goals in 34 Premier League appearances last term.
"He [Benteke] has qualities that you cannot lose over the summer," Wenger added. "I think he can be more dangerous this season as well."
