The Gunners were heavily linked with moves for a number of midfielders during the summer transfer window, including Real Madrid’s Sami Khedira – but Wenger opted not to bolster his options in that position.
Diaby made his first-team comeback after a lengthy injury lay-off as he played 67 minutes in the 2-1 League Cup defeat by Southampton in midweek.
Asked if he regretted not signing a defensive midfielder, Wenger replied: “Not at all.
“Abou Diaby is a natural resource that I have because he’s a top-quality player. If you look to find better quality players than Diaby on the market you will have big problems.
“He has not played for one-and-a-half years and I tried to find a solution that suits him and us.
“What’s happening is that he’s not at his best at the moment because he needs competition.
“He has not got that change of pace and the power in his challenges that are his strengths, but if I can maintain him without any injuries he will come back and it could be a very satisfying solution for him and us.”
