Toure is gaining experience ahead of completing his formal coaching qualifications.
He was the assistant manager at Ukrainian outfit Olimpik Donetsk earlier in the year and currently holds a similar position at Russian side Akhmat Grozny.
Toure is also volunteering at Tottenham, working alongside coaches Dean Rastrick and Chris Powell.
Arteta is happy for the ex-player to leave Arsenal's biggest rivals and continue his managerial education at the Emirates.
"He has my number because we spent some years together," said the Gunners boss. "He's a player I appreciate a lot and he has my number and can ask me the question.
"He certainly has the experience, the expertise and won a lot in the game to add value to the game for sure."
