I don't think any of those 3 are in for him TBH. Too much money, too little impact on the pitch. As good as he is, and he's very good, he spends more time in treatment than he does on the pitch.I dont think we are in for him. His agent is just trying to get him a move or Wolves are trying to create a market for him as they need the money.
I'd speculate that the most likely scenario is that a few clubs have made an enquiry, and these 3 are the highest profile.
Definitely Wolves, and his agent, trying to drum up interest, before P&S inevitably forces asking prices to drop.
Personally, I think they'd do well to get anything North of £40M for him.
