It's probably worth remembering that he hasn't gone anywhere or even said he's going anywhere yet mate. There's also the distinct possibility that if he is eventually sold, he'll go with the money men throwing in a free taxi ride in order to get him out of the door and get their hands on the cash.
To be totally honest I am less concerned about him going to another English club than I am either getting somewhere near his true worth (which is around 60 mill IMHO) and also the manager getting at least a decent portion of the money to re-invest. If it's a sale to Barcelona for 45 mill or a sale to Man City for 65 mill, I'd take the second one in a heartbeat over the first.
