The pair have hit the target in tandem so far, notching six between them in four games - including a goal each in Thursday's trouncing of Europa League opponents Petrolul Ploiesti.
Bony, 24, told the South Wales Echo: "Me and Michu are working well together.
"I like him, he always shows great technique and positioning. And we know a little more about each other every day and getting better and better with it.
"We talk a lot and getting to know him is good for me because it is not easy to come in and adapt in just a few games. And to start with we will miss some passes and chances because of communication.
"That's something we have to work on and we will both try to do better every time. And I think we can. Michu did very well last season and this season could be tough because now defenders know him.
"Maybe it will help me if defenders are looking at Michu. But everyone knows how we play and the team is more important.
"And I think and hope he can do better than last season to help the team.
"He is a good player and I hope he does stay like we think because he is very important to the team."
