With Aaron Ramsey returning to his best after a long-term injury, and Mikel Arteta arriving from Everton during the summer transfer window, the Cameroon star has featured in Arsene Wenger’s new midfield trio in Jack Wilshere's absence.
All three midfielders have been among the goals since the start of their campaign, and Song believes that they are growing more and more as a unit with every game.
"Our knowledge of one another is improving every day," he told the club's official website.
"It hasn’t been easy because Mikel only signed for us recently, but you can see what a good player he is and I’m really happy to be playing with him.
"Aaron’s doing well too, and we’re all still coming together and learning what works best. We’re all trying to help each other and that’s important. The more we communicate, the better we’ll get. if we’re constantly giving each other advice on the pitch then we can become a very good unit.
"Also we’ve still got Jack and Abou to come back, which gives us a lot to look forward to in the midfield."
The 24-year-old missed three of Arsenal’s first four games this season because of suspension but since his return he has featured consistently in the side and is content with his current form, adding: "I’m very happy, although you always want to do more.
"Last season I scored five goals and this time I’d like to score eight or 10, it would show that I’m improving a lot in that area.
"If you want to be a top player you need to keep pushing on, to keep improving every time. Under one of the best managers of the world I have that opportunity and I’m always trying to take it."
And Song has also given praise to Gervinho, who joined in the summer from Lille, and said he was not surprised by the Ivorian’s flying start at the Emirates, as he admired his new team-mate’s abilities at the French club.
"I watch a lot of the French league at home so I knew when Gervinho arrived that he was a very good player," he said.
"I’m not surprised to see him doing well here and I think there’s more to come. It’s not easy to come to the English league, it’s harder and stronger, but he’s getting used to it and I’m really happy to see him making a difference in games.
"Gervinho is a very quiet guy, not one who talks too much, but I think it’s normal that you look and listen when you arrive somewhere before saying a lot. I think he’s now coming out of himself and you can see it on the pitch too."
