The 20-year-old Arsenal midfielder agreed a six-month loan move back to Gresty Road on Friday, having enjoyed two loan spells with the League One side last season.
"I see those players that have moved on, that's football and good players will rise," he told BBC Radio Stoke.
"I hope that's the same for myself, I've come here to improve my game. I want to play football, and I know I did quite a lot of that last year.
"The only way you improve is by playing games and obviously Crewe were good to me last season so I want some more of that."
Aneke made 38 appearances for Crewe last season.
