Anything genuinely unethical or unlawful I'd have a major concern with. But until proven I'd assume he's a person who is very good at his job and very influential in the game.
And it's interesting that he seems to be a genuine strategic influencer in the game, not an order-taker, not a bottom-feeder. And I think very few agents get to the point where they have his power. Where he can seriously influence players to join certain clubs, where his say has such sway. I think it's interesting at this point rather than scary. If we get on the right side of him, maybe that's a good thing? Arguably it's worked very well for Wolves.
Levy has been known to do his own last minute price drops when bidding, so maybe he seems a kindred spirit.
