On a real though, I don't think the past crop of Russian players is too big a factor to consider.
Otherwise, you wouldn't have your Aubameyangs, your Weahs, your Mkhitaryans, your Adebayors, your Litmanens, your Yorkes...
If he's good, he's good.
I get what you're trying to say, but your examples don't really add up.
Aubameyang might play for Gabon, but he was born in France, and clearly is a product of France. Also, his dad played professional football in France and for the Gabon national team.
Mkhitaryan gradually worked his way up from Shaktar to Dortmund before he moved to the EPL.
Weah and Adebayor were both relatively unheard of players that Wenger gave a chance to that few others would. But Africa had also been creating scouting networks and sending players to Europe.
Litmanen might be Finnish, but he made his name at Ajax, and the Dutch League has long been a destination for players prior to moving to a big league.
Yorke is from Trinidad, but he played for Aston Villa for nearly a decade before he moved to ManU.
Golovin looks talented, but there are few examples of Russian players moving to the EPL and being successful. Pretty much everyone on their national team plays in Russia. Not a good indicator of Golovin being able to thrive in a much more competitive league.
