1) Where was Pochettinos agents quotes about him going for an interview with Spurs? Where were Mourinhos agents quotes about going to Utd? All of this stuff is leaked through intermediaries for any number of reasons.
This is different. People are actually saying and sharing that this Rob Janssen chap was on Dutch TV. Well if he was on Dutch TV, talking about Koeman (who's absolutely mahoosive over there) then where are the quotes?
2) A bit soon to dismiss it due to lack of coverage, the 'news' has only just broken.
It's been out there for three hours now. No one in England is reporting it and none of the big outlets in the Netherlands are either. One guy, supposedly reliable, has tweeted it. It could be true, it could not.

4) Didn't Reed say something similar re Clyne? I felt that interview he gave about contract talks a little worrying if anything, if everything was OK then why do they need to come out and say so? Could just be PR from the club to let them know we offered a new deal and it's out of their hands.
Granted, that did happen with Clyne. We'll see what happens with Koeman now. Seems odd to blabber on about being in agreement over ambition and the future and say we're at the stage of agents and lawyers after long meetings with Koeman if he had no interest in signing a new deal, though.
5) I don't personally, but people don't tend to put large amounts of money on these things at short odds if they've not heard something. Not enough time has passed for the market change to be due to a large number of people putting small bets on.
Gambling is a mug's game and there's no shortage of mugs. We'll see what happens.
