Russians are currently debating the more complex issue of whether Spartak Moscow's Brazilian striker Welliton should take citizenship and be welcomed into the national team.
"If the player and the FA are in agreement, what would be the problem? Look at what happens in European countries: there are Brazilians and Africans.
"But if naturalization has only one benefit - to improve results - it is fundamentally the wrong approach.
"It is important that the player loves the country he is going to play for. We must ask Welliton: is Russia in his heart? It is important for him to know the Russian language."
