Even though the Gunners have endured a difficult season, and find themselves in tenth place in the Premier League, Partey is adapting to life in North London.
The central midfielder believes Arteta has helped him evolve parts of his game, including his passing and chance creation.
"Mikel is helping me a lot. At Atletico, I played in a similar position," he told Stadium Astro.
"The system is not the same back there, you have to be well positioned to be able to go around your marker, and here Mikel is helping a lot because I remember, he said, 'You don't have to be in the same line and opposite the defender'.
"You have time to be able to do whatever you want and this is amazing.
"It's just as important, you need to keep it in mind and whenever your teammates have the ball, you know who you are in line with, who you are not in line with and this is helping me a lot."
