Swansea allegedly turned down a £30m bid from China in the last few days. IF that's true then I doubt we can get him in the summer. If they stay up, they keep him; if they go down presumably the Chinese teams will be back in for him, so the fee will likely get very silly very quickly. I rate Gylfi very highly and have often said he's a player I would like to see us pursue... but only up to a point. If the fee is crazy, you have to say no.

Presumably the player has some voice in this matter as well?
