I'm a big Wilder fan, but if we're actually looking at players like this guy, then I'm already really worried about the summer.
If he's not good enough for Birmingham, then he's not good enough for us. I know there's an exception in Duffy, but Trusty and Chong also played for Brum recently, before signing for us, and look at how shit they were/are.
As for doing well at Hearts, I reckon I could look a player in that league. I watched Hibs Celtic the other day and the quality is utterly dire. Most sides are League Two/League 1 at the very best, with Celtic/Rangers/Hearts at lower mid-table Champ standard. Who was that player Brum signed in the summer for nearly £10M? Kyogo? The guy who couldn't stop scoring for Celtic. He's got 1 goal in 28 games.
