The media just film it , its him doing it for the attention in my opinion and he absolutely loves it making him perfect for them. Running on the pitch to celebrate with the players , running into other manager technical areas , celebrating the awarding of penalties , celebrating with the players in front of the kop after a home draw, turning his back when penalties are taken not to mention the ridiculous gurning it's not a personality its attention seeking .
I appreciate your opinions on koeman but his reaction in the 3-2 Southampton win over the RS was I believe directly in response to Klopp's behaviour and I think you can read into Pulis' comments after the celebrations in the draw. As I say I'll expect you to disparage the two managers I've just mentioned but that's not the point it's klopp's behaviour that's apparently irritated one or two other managers and I'm sure they're are probably a couple more.
As for annoyingly respectful and agreeable his berating of the fourth official , which would absolutely have seen mourinho banned, and the mask slipping against a journalist post game when the RS hit a poor run of form would argue against your point .
I'll agree with your earlier points that he's done well, I think Klopp has done a pretty good job with them especially if they get the top four but you seem to have fallen for this "oh what a character " BS that the media peddle . For me it's pathetic journalism and I find it lazy but given it's the RS it doesn't surprise me.
