Aneke, a tall and powerful central midfielder, says Diaby is the man he looks up to most in the current squad.
"He is injured at the moment but I love the way he plays," Aneke told Arsenal.com "He's got lovely feet and is a physical presence like myself so he is somebody to look up to.
"I speak to Abou when I can. Hopefully he is coming back and can do well for the first team again.
"Obviously training with the first team is a good experience every time because they are bit sharper and bit quicker so it feels like you can play a bit faster.
"They are all good players and they make you up your game a little bit more."
