No idea, that's not really mentioned but I have my own conspiracy theory about that...
I think FSG are still considering Rodgers vs Klopp. All of a sudden, one of Klopp's mates has come out saying that he wants to be coaching in the UK and would be keen on the Man United job if it ever came up which to me sound like someone trying to force Liverpool's hand.
I don't buy into the sabbatical thing but if it's true, it could work out for us.
1 - Rodgers gets it right and by January we're challenging and playing well.
2 - He gets it wrong, he's sacked and Klopp comes in then after 6 months off.
There are no big jobs available at the moment so unless a huge job comes up (United, Arsenal, City, Barca, Real, Juve etc. I don't see Klopp being in a rush)
