Scotland striker James McFadden is keen to leave Birmingham following their relegation to the Championship, according to his agent.
Agent Willie McKay said: "James has told me that he wants to leave.
"He is happy when Alex McLeish gave him an opportunity to play first-team football every week but it's a short career and he wants to play at the highest level."
However, Blues manager Alex McLeish is keen to keep hold of the former Motherwell star and said: "We want to keep hold of our best players and James is absolutely vital to our plans."
McFadden, 25, signed a three-and-a-half-year contract when he arrived at Birmingham and has scored four goals in 12 games.
