This is a good post. The only thing I would say though is in the Kangaroo court of the internet what you often find is a lack of balance or a fair understanding of different things.
Eek said we were heavily in for Mata and Witsel. Neither signed. He also mentioned Stones was likely to go, Barkley and Lukaku stayed. That was true. He intimated at different moments Stonebridge Cross wasn't the preferred option but a Docklands site would be- again looking true. He gave us the day Martinez would be sacked, when he was. He told us we would be getting a DOF in and we did. He stated very early on we were very impressed with Koeman, and even when it was delayed confirmed he would be our man. He made it explicitly clear that Moyes would not be given the job. The list could go on.
I don't say that to suggest he is always right, or people have to listen to him. We live in a free society and people have the right to choose what bits of information they do or don't listen too. What can't and shouldn't be mistaken though, is that he has got some right sand some wrong, but the tendency is for him to be right more often than not. Maybe he is just very lucky, but I would imagine he is well connected.
But yes I have rambled on, however the salient point here, is when people make the point of Mata and Witsel it would normally be fair to acknowledge there are numerous other examples when he got it correct. That doesn't happen, which is a tad frustrating as it gives a skewed perspective. If people want to feel he's a conman (or equivalent) thats their opinion which they are entitled too, but lets at least have a fair hearing of all the evidence.
