No. He's a fecking grifter. An aggregator. That's his tactic. Reword information found by other journalists, add vague, non disprovable tidbits, post the same Tweet several times over few days for maximum retweets.
His business model is grand and he's very successful at it but its getting to the point of arguing wrestling is real if you can't see that's what he does. If people genuinely think he randomly became the guru of world football transfers two or three years ago then I don't know what to say.
You either think this man is connected to every agent and every player at every club in every country and is therefore in a position to give exclusive scoops on every single major transfer in a way that you're not minutely suspicious about - or you think he's a grifter whose successfully made a name for himself cleverly exploiting social media and fans insatiable desire for transfer news.
