Kanchelskis has been hugely impressed by the Irishman in Russia.
He told the Sunday Mail: "I've got to give McGeady a perfect score for his performances this year.
"I'd give him 10 out of 10. There haven't been many better. His quality on the ball has been excellent, his pace and mobility is now Spartak's biggest threat.
"I like his attitude. He's a winner, he doesn't give up on anything.
"This is a quality that all top professionals needs, but not every talented footballer has it. McGeady has a typical British mentality - a classic winger.
"Before he came here people said he wasn't a team player but I can't agree with that.
"He plays 100 per cent for the team. It's now clear this is a player with a big, big future."
