Aneke is returning to his best form at Crewe.
Leitch-Smith told The Sentinel: "Chuks has great vision and great passing. If you make a run you can be confident he'll spot it and be able to pick you out.
"I played with him a few times last year as well, and I know where he's going to pick up the ball. He knows what I'm going to do and he can find you.
"He must be one of the best players in the division for being able to do that. He's come from Arsenal so it's no surprise. He always wants to get on the ball.
"He's a dream partner really and hopefully we can get some more goals."
