Lets be fair, i know Mitten has a lot of contacts, but the fact remains that he has absolutely NO IDEA what de Jong has told ten Hag and vice versa. He's probably well more connected than most journos, but i think this is a transfer where the only ones who know whats going on are those involved (United board, ten Hag, de Jong, Barca). Anything outside of them are probably being fed what those telling them want them to hear. Hence why there are so many reports being flung around in Spain. Thats my take on it anyway.
Unless Mitten has a direct line to someone directly involved, and by that, i mean privvy to the private conversations, he likely knows as much as someone such as Romero etc
