The pair have kicked off the season in excellent form.
Arteta said, "I think the front players need to create a certain chemistry between them and that feeling that when they look at each other in the eyes, they understand each other, they communicate on the pitch to see what they are feeling.
"I think we are getting that with them at the moment. Not only them, but with Willian as well and the way he's come in the team straight away. With Pepe, Bukayo - when he's playing there - and with Reiss. It's really important, it's something we try to promote in training as well. Hopefully they can keep linking and improving those relationships between them."
