Well from what I've heard it was quite clear that he was more than happy to manipulate the Hearts situation in order to double his wages at Fir Park. Take from that what you will, but I have no reason to doubt it. Nor have I seen or heard anything from McGhee to suggest it would be out of character.
Like a few on here, I have a strong dislike for the complete disrespect and unprofessionalism Mark McGhee displays on a regular basis. I don't buy the "ah, but who would you replace him with?" argument that gets floated about regularly from those defending McGhee. But if that's the question, then I would at least be happier with someone in charge who would be willing to put his all into long-term success at Fir Park, rather than just seeing how much he can add to his CV before he jukes us.
