The France international joined the Gunners for £2million from Auxerre in 2006, and has often shown glimpses of his raw potential.
"This time I have not been called up by France and I do not play that much for Arsenal," said Diaby.
"I need playing time. I thought that I would continue [to play] after I scored (against Derby) but it did not happen.
"I remain patient and do not give up because I know that my chance will come.
"Arsenal's team is doing well so I have to show patience and it will be unlocked then. I do not regret my choices. Those things happen.
"The situation is like this today but it can change tomorrow. The players that are on the pitch are not automatically better than those who are on the bench, but they do their job very well.
"The season is long so I do not plan a move yet. Maybe later if it continues, but not in January."
