There was no source! You really are giving this journalist far more credit than is due. it was purely his opinion given as fact. There was no new evidence or quotes. it was absolute horseshit. And the fact it was dismissed so quickly proves it. If the two sides are playing hardball against each other and are using the press to try and get a better deal, as you are suggesting (implying that the source was defoe's agent), then surely Johnson would keep quiet about it all and not declare his position to everyone at the very next opportunity he gets. He is interested. He's made that clear. Therefore the article is bullshit. I'm absolutely convinced that what has happened is that Johnson gave a really naive and stupid answer to a question in a press conference, which led to a journalist writing a piece about him not being interested (which is what a lot of other people also GUESSED).
You've just completely made this up with no knowledge
How on earth do you know there is no source?
