They are all extremely unreliable they all use external sources of media (mainly from papers and TALKSPORT - LOL) that are just rumours and nothing more. Christian Larrson is an ex-scout and talks to agents, he has a lot of contact with them, has their email and talks to them on regular basis. He's one of the most reliable sources for transfer news.
Maybe so, but there is not a chance that it is 100% done and dusted as things could very much change.
I highly doubt he will go Chelsea with the FFP rules coming into place and him probably costing upwards of 40m.
