There's no such things as ITKs. I remember a certain ex-player telling me that Pienaar was signing for Chelsea, he didn't by the way.
Of course there are people who are ITK, the ones who are most ITK probably wont share info with a wide audience because the better the source the less likely they will want it leaked who it is. The club and Moyes are quick to try and find sources who leak things.
Chelsea bid for Pienaar and he was possibly going to go there but Spurs came in and he thought there was more chance of game time there...not the best guess but even so that ITK might have given accurate info at that time but situations change. Fernandes couldnt have been any closer to signing for us, but within a few hours he was a Valencia player. An example of how something can be happening but things change, doesnt always make what someone has told you or a rumour you believed a lie.
