Russia coach Guus Hiddink believes Premiership clubs should have foreign player limits.
He said: "I don't know, I cannot predict the future."
But he did have one word of warning for the English game regarding the number of foreign players in the Premiership.
He said: "I have heard some people in the FA have concerns about the future of English players. I can imagine that everybody has that concern.
"If you compare the situation to Russia, in a few years there will be a maximum of four foreign players in the club sides."
