A bit of Adu
Not being a follower of Major League Soccer, I've no idea how good he is. Sure, I've seen the clips on YouTube, but you have to ask yourself, if he's that good, why didn't Alex Ferguson sign him?
Normally, I'd say the Scottish league is inferior, and a bad choice for high profile players. However, in Adu's case it might be perfect. The demands on him wouldn't be so high, and if he did well, it would act as a showcase for his entry into the Premiership, perhaps even to Man United.
