I don't know if it's McFadden or his manager/agent, but any time he is looking for a new club it always seems to take months to secure a deal.
No disrespect to the guy, but if he's not cutting it at QoS I'm not sure what standard of overseas team will be interested.
Having said that, a league where the style of play is a less frantic than the Scottish game might help extend his career an extra year or two.
