Scotland boss Craig Levein is unsure of where to play Birmingham City attacker James McFadden.
McFadden is waiting to hear if he will play against Liechtenstein tonight.
Levein said: "The best teams in the world have extremely talented players who work their backsides off. We have a lot of extremely talented players.
"The questions everyone asks are 'Is McFadden a maverick?' and 'Where do we play him?'
"Is it a gamble to play James? I think previous managers have wondered what to do.
"Everyone recognises he is an extremely talented boy. For me, he has all the talent in the world.
"But getting him into the way of thinking that everybody has responsibility is a challenge."
